What is the Difference Between Overmolding and Insert Molding?
https://www.key-plast.com/what-is-the-difference-between-overmolding-and-insert-molding.html
Plastic injection molding is one of the most widely used processes for manufacturing high-quality and extremely precise parts. The process is known for its multiple advantages. Consequently, a wide range of industries have adopted this part manufacturing method. There are many types of injection molding technologies currently in use, depending on the parts to be produced. Among the many types, overmolding and insert molding are the two most common injection molding technologies.
1. Overmolding
As the name implies, overmolding is a process of molding one material on another. The first component is made in an injection mold and then placed in the second mold, where overmolding material is added. This technology combines a variety of plastics to achieve practical or aesthetic purposes. For example, people may use plastics of different hardness to mold soft plastics over hard plastics to make the parts easier to grasp. The use of multiple colors of plastic in overmolding parts can also distinguish the products from those of other brands. Overmolding is often used on the handles of tools such as screwdrivers, electric drills, or toothbrushes.
The advantages of overmolding injection molding are:
(1) Improve material flexibility
(2) Long service life
(3) Enhance security
2. Insert molding
Insert molding is a subset of injection molding technology, similar to overmolding. Before the actual injection molding, the metal part is put into the mold cavity, and the insert is accurately positioned in the mold by manual operation or mechanical arm. Then the mold is closed and the plastic is molded on the insert to form a part. Most of the finished parts produced by this method are a combination of thermoplastics and metal parts, which are often used in aerospace, automotive and medical fields.
The advantages of insert injection molding are:
(1) Reduce assembly and labor costs
(2) Reduce the weight of parts
(3) Shorten assembly time
The above is the difference between overmolding and insert molding. Both have their own advantages and applications. The corresponding technology can be selected according to the type of parts to be manufactured.

Types Of Plastic Injection Mold Polishing
Introduction to the plastic injection mold polishing
These days, industrial products are developing in the direction of product high quality as well as product diversification, in this way mold quality is going to have an influence on product quality directly, so improving mold quality has become an important task. Plastic injection mold polishing is a technology that helps to obtain a smooth mold surface. It is very different from the surface treatment of other industries. It has higher standards for polishing process, smoothness, and geometric accuracy.
Types of plastic injection mold polishing
(1) Mechanical polishing
Mechanical polishing is a method of removing the protruding part on the workpiece surface by cutting or plastic deformation on the surface of the material to obtain a smooth surface. Whetstone, wool wheel, and sandpaper are usually used for manual operation; if the surface quality is high, the processes of ultra-precision grinding and polishing should be used. This technology can reach a surface roughness of Ra0.008 μm, which represents the best value for mold polishing.
(2) Chemical polishing
Chemical polishing refers to the plastic injection mold polishing process of immersing a material in a chemical medium to ensure the micro-protrusions on the surface of the material dissolve before the dents to obtain a smooth surface. The method can be used to polish workpieces with complex shapes and can polish multiple workpieces at the same time, with high efficiency. The surface roughness that can be obtained by chemical polishing is usually Ra 10 μm.
(3) Electrolytic polishing
The basic principle of electrolytic polishing is the same as that of chemical polishing, which is to selectively dissolve the surface of the material to form a smooth surface. Compared with chemical polishing, it can eliminate the influence of the cathode reaction to produce a more significant effect.
(4) Ultrasonic polishing
Ultrasonic polishing is a method that uses ultrasonic vibration of the tool part and uses abrasive suspension to polish brittle hard materials. The workpiece is immersed in the abrasive suspension, and then placed in an ultrasonic field together with the suspension, and the surface of the workpiece is ground and polished by the action of ultrasonic waves. Ultrasonic machining has a small macroscopic force, so it will not cause the deformation of the workpiece.
(5) Fluid polishing
Fluid polishing relies on the flowing liquid and the abrasive particles it carries to erode the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure, the polymer in the medium flows at low pressure, and the abrasive particles are usually silicon carbide powder.
(6) Magnetic grinding and polishing
Magnetic grinding and polishing of plastic molding china refer to the use of magnetic abrasives to form a brush under the action of a magnetic field to grind the workpiece. The method has high processing efficiency, good quality, and easy control of processing conditions. The surface roughness obtained by this method can reach Ra0.1 μm.

Two Shot Molding Process
Two shot injection molding has two stages in the whole process.
Firstly one shot of materials is injected into a mold and cooled to form a solid part. Secondly, the mold opens and rotates 180 degrees and then closes. The second shot of materials is injected into the mold, through or around the first molded part. After sufficient cooling, the mold opens and the multi-resin molded part is ejected. 2 shot moulding has key factors as below:
Melting temperature for the materials
Wall temperature for the mold
Injection speed for the molded parts
Delay time between injections
Temperature of the components
Two Shot Molding Process
Two Shot Injection Molding Design Guide
The mold used in two shot molding consists of different tool sets. In rotating platen settings, these two shot injection molding tools share the same core, but different cavities. The runner must be designed to close during its inactive forming step.
Wall thickness is an important two shot molding design consideration when designing parts for a number of reasons:
Due to the molding pressure from the second step, the substrate wall should be thick enough to withstand the force without collapsing.
Walls should not exceed traditional thickness guidelines to produce effects attributable to irregular cooling.
To ensure accurate and thorough flow of 2k molding material into all parts of the cavity, the wall thickness should not fall below a certain minimum value.
Ideally, materials should be injected in a certain order, taking into account the following factors:
The first shot should be the harder plastic of the two.
If transparent and opaque materials are used, inject transparent materials first.
Generally speaking, the material with higher temperature is injected first.
For mold frame and insert design:
Make sure the mold can be rotated 180 degrees.
Any insertion should be symmetric.
The push rod plate and thimble are stabilized by a return spring to prevent damage during mold rotation.
The cooling system of double shot molding must be able to function adequately on the first and second shots.

Plastic Injection Mould Tooling
https://www.key-plast.com/plastic-mold-making/
Plastic molds are tools that are matched with plastic mold making machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the wide variety of plastics and processing methods, and the complex and simple structures of plastic injection mold making machines and plastic products, the types and structures of plastic molds are also diverse.
What Is A Plastic Mould Tooling ？
Injection molding tooling is at the heart of plastic injection mold making. Whether it’s a complex operation or simple part, plastic mould tooling – more specifically, tooling design – determines the quality of the injection molding process and the parts produced.
Scientific molding is crucial. It provides largely accurate process of plastic injection mould making that lead to top- quality corridor with constantly tight forbearance and unremarkable confines.
Injection molders and toolmakers experienced in the application and use of scientific molding help clients steer away from arbitrary injection molding tooling design decisions in favor of data-based precision. It sounds elementary, but the factors that could skew injection mould tooling design, engineering, and outcomes are numerous. Engineers specially trained in scientific plastic injection mold making can readily identify and help prevent potential missteps.
Plastic Mould Tooling Capabilities
Plastic injection molds are used when there is a requirement for male or female threads on a plastic component.
An assembly of heated components used to inject molten plastic into the cavities of the injection molding mold.
Includes mechanical action incorporated into the design when a hole, slot, undercut or thread is needed that is not perpendicular to the parting line.
Provides one parting line and the plastic injection moulds splits into two halves; the sprue, runners, gates and cavities are all on the same side.
Plastic Mould Tooling Protection Investment
Preventative：Once a injection molding mould has run a set number of cycles, examinations, conservation and cleaning should be performed. Different types of mold in injection molding age at different rates, so scheduling conservation needs to be proved precisely. Our knowledge and experience gives us the capability to determine the stylish mold conservation schedule specific to each injection moulding mold.
Maintenance：Injection molding tool repairs can be costly. This means it is critically important for injection molds to receive regular maintenance; this is simply the best way to protect your investment and maintain consistent production of quality plastic components. With our on-site plastic injection mould tooling facility we provide quick and efficient mold repairs or revisions.
How To Make Injection Molds？
Injection molding is by far the most protean of all injection molding ways. The presses used in this process vary in size and are rated grounded on pressure or heftiness. Larger machines can injection earth auto corridor. Lower machines can produce veritably precise plastic corridor for surgical operations. In addition, there are types of injection moulds that can be used in the plastic molding and manufacturing process, adding its inflexibility for contrivers and masterminds.The process itself is fairly straightforward; still, there are numerous advancements and customization ways that can be used to produce the asked finish and structure. Plastic injection molds, which are generally made from sword, contain depressions that will form the corridor. Melted plastic is fitted into the earth, filling the depressions. The mold is cooled, and the corridor are ejected by legs. Injection moulding raw material list can be varied.
This process is analogous to a jello mold which is filled also cooled to produce the final product.The mold making costs in this system are fairly high; still, the cost per part is veritably provident. Low part cost along with resin and finish options have all contributed to injection molding’s fashionability in moment’s manufacturing geography.
Mold Making
As a professional injection molding supplier, we complete all plastic injection mould making, from cutting materials to cavity carving, and then to the final assembly. We have advanced high-speed milling machines, electric discharge machines, wire cutting machines, and engraving machines to ensure that the machining accuracy can meet the requirements.
Mold Making
Mold Trial
Generally, the mold is not directly regarded as the final product when it is designed, because it will have such or other defects after it is produced. However, this type of defect There is no guarantee that they will be completely avoided before manufacturing. During the manufacturing process, there may be phenomena that cannot be stored and processed. Therefore, it is necessary to go through the trial model, and then analyze, evaluate and optimize the samples produced by the trial model to meet the requirements. High quality requirements. However, most of the defects of plastic mould tooling products are caused during the plasticization and injection molding stages, and may also be caused by improper manufacturing of plastic molds. Therefore, in order to avoid product defects caused by mold design in injection molding process steps, it is necessary to analyze when making molds. Mold design and process parameters.
Mold Trial
Sample Confirmation
The acceptance of the part shall be carried out at least 16 hours after the completion of the molding of the plastic part or the required post-treatment.
1. Inspection of product matching size
The matching dimensions of injection molding mold products refer to the matching dimensions between products or between injection moulding products and related components, including partial matching dimensions and overall relative position dimensions.
2. Trial assembly inspection
When the inspections of basic dimensions, external dimensions, and matching dimensions are completed and the design requirements are basically met, trial assembly inspection can be carried out. This is a very important means in product inspection. It can verify the matching dimensions and verify the space surface.
3. Injection molding quality inspection
When the pre-installation meets the requirements, the apparent quality of the part needs to be comprehensively inspected. At this time, the apparent quality refers to whether the apparent quality meets the requirements under the condition that there are no common defects.

Injection Molding Surface Finish
https://www.key-plast.com/injection-molding-surface-finish/
Do not use the finest whetstone, sandpaper, or abrasive polishing paste at the beginning of mold polishing, as you can't throw away the rough lines. The living surface polished in that way looks very shiny, but when you take a side view, the rough lines appear. Therefore, it is necessary to polish from coarse whetstone, sandpaper or abrasive polishing paste, then change to finer whetstone, sandpaper or abrasive polishing paste for polishing, and finally polish with the finest abrasive polishing paste. This seems to be cumbersome and there are many processes. In fact, it is not slow. One process after another, the rough processing lines in the front are polished off, and then the following injection molding process step is carried out without rework, and the injection molding surface finish can meet the requirements with one step.
Textured Finish
Injection molding texture surface finishing is to create various patterns on the surface of different metal products through the action of chemical potions, such as sand patterns, stripes, images, wood patterns, leather patterns and silk patterns. Different technical processes produce different texture styles.
Polishing
Injection mold polishing has two purposes; one is to increase the smoothness of the mold, so that the surface of the product from the mold is smooth, beautiful and beautiful, and the other is to make the mold easy to demold, so that the plastic will not be stuck on the mold and cannot be taken off.
Sandblasting
Sandblasting is to shoot quartz sand to the surface of the mold through an air gun with a certain pressure, thereby forming a layer of frosted surface on the surface of the plastic mold. When a plastic mold injects a product, it will form a matte effect on the surface of the product. Generally, sandblasting is divided into two types: fine sand and coarse sand. For sandblasting, the surface of the plastic part is easy to wear off.

Injection Molding
https://www.key-plast.com/injection-molding/
Plastic Injection Molding
Plastic injection molding is a method of making plastic products. The molten plastic is injected into the mold by pressure, and then cooled and molded to obtain various plastic parts. There are mechanical injection molding machines dedicated to injection molding. The most commonly used plastics are polyethylene, polypropylene, ABS, PA, polystyrene, etc.
Different Types of Injection Molding
Two Shot Molding
One category of injection molding that manufacture multi-color or multi-material components or parts with no extra injection or assembly process.
Insert Molding
One category of injection molding that allows custom components to be inserted into the plastic molded parts, such as threaded metal inserts.
Over Molding
One category of injection molding that integrate different materials, like rubber or silicone, into existing plastic parts, such as the soft elastomer material on the handle of a toothbrush.
Custom Injection Molding
When considering custom injection molding, it's of great importance to assess the complexity level of your project and let that dictate the customization level you need not only from the injection mold toolings themselves, but from front-to-back in working with molders.
Custom injection moulding depends on multiple scientific methods, analytical tools and injection moulding process technology in order to meet the precision and performance requirements for complex plastic components and applications. Although faster time to market is a definite consideration for custom injection molding projects, it isn't pursued at the cost of part design, injection moulding material selection, mold design and injection moulding process control. In order to achieve product design and end-use goal accurately, custom injection molders will use these key product development stages to inform choices about the appropriate injection moulding process step by step such as scientific molding, insert molding, multi-shot molding, overmolding, etc.
What Is Injection Moulding Used For?
Injection moulding application: Injection molding involves injecting hot, molten plastic material into a mold, which is then cooled and solidified to form the product. Injection moulding method is suitable for the mass production of complex products, especially in the field of plastic processing that occupies a large proportion.
Injection Molding Process Steps
Step 1: The tool closes and resin pellets are fed from a hopper into the barrel, which signifies the start of the injection moulding process steps.
Step 2: The screw rotates to auger the pellets forward toward the tool and resulting friction plus barrel heaters make pellets melt. The screw is pushed forward and injects the material at the force and speed necessary to properly fill the tool cavity.
Step 3: After the tool cavity is filled, the resin must be allowed to cool.
Step 4: When the injection moulding plastic part is cooling within the tool, the screw retracts and reloads with melt in order to prepare for the next injection.
Step 5: As long as the molded material reaches its ideal ejection temperature, the tool opens and the part is pushed out by the forward motion of the ejector rod and pins.
Injection Moulding Material
ABS(abs molding): One thermoplastic created by the material of emulsion, with a relatively low melting temperature, and resistant to corrosive chemicals.
Common Application: Enclosures.
Acetal(POM/Delrin): One thermoplastic which is resistant to liquid absorption and chemicals and used to be injection molded.
Common Application: Bearings, bushings, dispensing components.
Acrylic(PMMA): One transparent polymer with excellent tensile, bending strength, less cost and comparable properties to polycarbonate.
Common Application: Clear enclosures, light pipes and LED lights.

How does Keyplast Solve Injection Moulding Problems For Giropes?
Firstly, Giropes said it was hard to find suppliers to provide low-volume plastic mold tooling runs, but Keyplast could do it. We could provide one-stop service from prototype to low-volume production or high-volume production in the injection molding electronics industry. To help Giropes develop new products, Keyplast was willing to work with Giropes, help to modify the drawing and run the first small batch of 100 pieces.
Secondly, Keyplast provided Giropes with a specific and well-organized DFM report. Based on the report, they could review, comment and make revisions on the designs.
Thirdly, the electric weighing parts required sliders for the holes and mental threaded inserts for the plastic parts. Keyplast cooperated with our injection moulding and post-processing team to have the injected parts with threaded inserts. Giropes approved the products and established solid business relationship with Keyplast.
