Injection Molding and Injection Molding Tooling Services

What's injection molding

Injection molding is the most economical way for plastic prototype manufacturing in large scale, by injecting molten material (usually plastic or metal) into a mold to produce parts. Here is a brief overview of the process: Prepare a mold, which is a metal block with the shape required for the part to be produced. Then close the mold, inject the molten material into the mold cavity under high pressure, and the material cools and solidifies inside the mold. Once solidified, the mold opens and the finished part is ejected. The mold closes again, and the process is repeated to create multiple parts, which can be repeated hundreds or thousands of times. Injection molding is well-suited for mass-producing parts with complex shapes and high precision. It is used in various industries such as automotive, medical, consumer goods, and packaging. However, the process does require an initial investment in mold making, which can be a significant expense for custom or complex molds. In addition, the machinery and equipment used in injection molding are generally quite costly, but considering the high output and efficiency of the process, the cost is justified.At Brightstar, we offer a range of injection molding services, from low volume prototyping to low cost injection molding production, using thermoplastic plastics （TPE）, thermosetting plastics, or metals. Our team of experienced molding experts can guide you to the right solution, whether you need a quick prototype with aluminum tools or a more durable solution for larger production runs. Unlike many molding companies, we do not specify a minimum order quantity.

Application of Injection Molding parts

CNC machining is an automated manufacturing process that can produce a variety of complex precision parts with high accuracy, covering airplane parts (such as engines, landing gear, satellite parts，Aircraft Parts，rivet), custom car parts (such as auto prototype, engines, gearboxes, brake systems，custom chassis), custom motorcycle parts, motorcycle prototypes. Medical devices and implants (such as surgical tools, implants, and medical device prototyping), machinery and equipment parts (such as gears, bearings, gaskets, flanges and millions of machined aluminum parts), electronic equipment parts (such as electronic prototype, mobile phone prototype housings, laptop computer custom components, electronic parts) and precision instruments (such as watch parts, electrical components, connectors, switches). It is also used to make molds and fixtures to support other manufacturing processes such as injection molding.

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 similar to overmolding, but the substrate does not have to be plastic and does not have to be produced by injection molding.

Secondary Molding
Overmolding uses injection molding to create parts made from multiple materials.

Injection Molding Surface Treatment

name Can BeApplled with
Spraying

Applying organic coatings by brushing or spraying to mask or create special painting atmospheres.
Printing

Including screen printing, pad printing, and intaglio printing, used for printing characters and patterns.
Film Transfer

Pre-printed characters and patterns are transferred onto a thin plastic film; there is also the in-mold transfer method which is done inside the mold.
Painting

The surface of the molded product is activated through pre-treatment before metal electroplating, which can achieve a good metallic luster and conductivity.
Vacuum Metallization

A method that uses a pressure difference to apply a thinner film compared to resin electroplating through vapor deposition.

Quick Guide to CNC Machined Part Design

Tips for CNC Machined Part Design:
Simplify Design
Eliminate unnecessary high precision and unneeded tight tolerances, or design for deep and narrow holes that are best machined through EDM, as these can be prone to failure and increase costs.
Avoid Sharp Corners and Points
Sharp corners and points are difficult to machine and can lead to tool damage. A radius of at least 0.5mm is typically recommended to replace sharp corners. As well as considering various thread types, for internal threads, the recommended minimum size is M2, and M6 or larger is recommended to ensure the reliability of threaded connections
Use Standard Sizes
Whenever possible, use standard sizes and tolerances to minimize the need for custom tools.
Communicate with Manufacturers
Communication with manufacturers during the design phase is essential to ensure the manufacturability of the design. Manufacturers can provide feedback on material selection, tolerances, surface treatments, and other design for manufacturability (DFM) considerations to ensure the design meets manufacturing and functional requirements
Use 3D Modeling Software
Use 3D Modeling Software: 3D modeling software, such as SolidWorks, AutoCAD, or Fusion 360, can help designers create detailed part models and anticipate potential machining issues. These programs typically include tools for analyzing part geometries and plugins for generating CNC code, ensuring that the design can be seamlessly machined on CNC machines.

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.
