Injection Molding and Injection Mold Tooling Services

What's injection molding

Injection molding is an economical method for mass - producing plastic parts by injecting molten material (usually plastic) into a mold. The process involves feeding raw materials into the hopper of the injection molding machine. The material is then heated and melted into a flowing state and pushed by the machine's screw or plunger through the nozzle and gating system into the mold cavity, where it hardens and takes shape. The key stages include mold closing, injection, holding pressure, cooling, mold opening, and part ejection. This cycle is repeated to produce hundreds or thousands of parts. Injection molding is ideal for producing complex - shaped parts with high precision and is widely used in automotive, medical, consumer goods, and packaging industries.

Plastic and metal materials for injection molding

The key points of the injection molding process:

1. Consistency, the parts produced by injection molding are uniform, which is crucial for quality control.

2. Fast production, once the mold is made, parts can be produced quickly, making it ideal for mass production.

3. Material diversity, a variety of materials can be used, including different types of plastics and metals.

4. The ability to produce complex geometries, detailed and complex shapes can be formed in a single operation without additional assembly.

Application of Injection Molding parts

Injection molding offers extensive applications across various industries, including but not limited to automotive, electronics and electrical appliances, medical devices, and industrial equipment.

Automotive Industry: Injection molding produces car interiors (dashboards, door panels, seats), exteriors (bumpers, lamp covers, emblems), and functional parts (water tanks, pipes, fuel tanks). It also supports lightweight materials for new energy vehicles.

Home Appliance Industry: Widely used for casings and internal parts of TVs, refrigerators, washing machines, and air conditioners.

Medical Device Industry: Essential for disposable devices (syringes, infusion sets) and medical equipment casings.

Electronics Industry: Key for casings of phones, computers, keyboards, mice, and MP3 players, relying on mold design, material selection, and processing.

Industrial Components: Produces gears, valves, and connectors.

Injection Molding Product Examples

Injection molding is widely used across various industries due to its batch production capabilities and cost-effectiveness. This includes automotive parts such as dashboards, bumpers, headlight covers, and more. Medical supplies: Including disposable syringes, handles for surgical instruments, housings for hearing aids, etc. Electronic device housings: The plastic casings for mobile phones, computers, televisions, and other electronic devices are often produced through the injection molding process.

Injection Molding Materials

Brightstar can mold any commercially available thermoplastic, including ABS, Acetal/POM, ASA, HDPE, HIPS, PETG, LDPE, Nylon, PBT, PC/ABS, PEEK, PEI, PET, PMMA, PBT glass-filled, PEEK glass-filled, Polycarbonate, Polycarbonate glass-filled, Polyethylene, Polypropylene, PPA, PPO, PPS, PPSU, PVC, Rubber, SAN, Silicone, Thermoplastic Elastomers, TPU, and TPV, etc.

 

In addition to basic injection services, we also offer two processes - overmolding and insert molding.Both of these processes are useful in specific situations.

Insert molding
Insert molding is like overmolding, but the base part doesn't have to be plastic or made by injection molding. For example, it can add a plastic coating to a metal part. It's often used for tools like scalpels, where a metal blade is embedded in a plastic handle, or for parts with bushings, clips, and fasteners placed inside the mold.
Overmolding
Overmolding is a process that creates chemically bonded multi-material components by adding a layer of injection-molded material onto an existing part. After the first injection molding process, the product is removed once it has cooled and is then placed into a second mold for a second injection. This causes the two plastic parts to be encapsulated together. It can be used to build layered components or to add a durable outer layer to existing plastic parts. This method is more cost-effective than separately manufacturing and assembling the parts.

Injection Molding FAQs

What are the advantages of ABS prototype in rapid prototyping?

ABS prototype can undergo a variety of post-processing processes, such as machining, polishing, grinding, filing, drilling, painting and bonding, which have a good finish after these processes. ABS is suitable for a wide range of prototyping applications, especially aesthetic prototypes and end-use parts

What are the requirements for materials in injection molding?

Good fluidity. Appropriate thermal stability. Compatible with mold material.

How to solve the demolding difficulties in injection molding?

Improve mold design and increase demolding slope. Adjust mold temperature. Use appropriate release agent.

What is injection molding?

Injection molding is generally a plastic rapid prototyping process, it involves heating a thermoplastic or thermosetting plastic material to a molten state and then injecting it into the cavity of a closed mold, where it cools and solidifies to form the desired part.

What are the advantages of injection molding?

High productivity: suitable for mass production. Precise dimensions: capable of producing parts with complex shapes and precise dimensions. High material utilization: less material waste. Good surface quality: capable of producing smooth surfaces. High strength: capable of producing high-strength parts.

How quickly can parts be produced using injection molding technology?

The first step in our injection molding service is to design the injection mold. How long this takes depends on the complexity of the project. It usually takes as little as a week or as long as several months.

What are the common defects in the injection molding process?

Insufficient filling: incomplete parts. Warpage: inaccurate part shape. Weld lines: marks where different molten plastic streams meet. Burn marks: black rust-colored discoloration on the surface or edge of the part. Jet marks: wavy serpentine patterns on the surface of the part. Voids: small cavities inside a part. Delamination: the peeling or flaking of layers inside a molded part.

How to avoid burn marks in injection molding?

Reduce melt and mold temperature. Reduce injection speed. Implement an effective exhaust system.
