Rapid prototyping plastic injection molding
Rapid molds and production tooling, ranging from 1-500k units, T1 samples as fast as 10 business days.
Overview: How Injection molding works?
The Basics Of Injection Molding Service
Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould.
Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.
After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part.
How Injection molding Works
The sequence of events during the injection mould of a plastic part is called the injection molding cycle. The key steps in the injection molding cycle are:
- Clamping: The two sides of the mold are closed and clamped shut.
- Injection: The material is fed into the machine and pushed towards the mold. While this is happening, the material is melted by heat and pressure. The plastic is then injected into the mold 鈥 this is called the 鈥渟hot.鈥
- Cooling: The plastic in the mold cools and solidifies into the shape of the part.
- Ejection: After the part cools, it is ejected from the mold.
Types Of Injection molding
There are several important moulding variations including, but not limited to:
1. Plastic injection molding
- Thermoplastic Injection Molding
- Insert Molding
- Overmolding
2. Metal injection molding

Injection Molding Processes
We design and manufacture tools, dies, and molds for rapid tooling for prototyping to advanced mold making for production runs. We can make a coated layer with one material(Like rubber) on surface of another material(Hard plastic), this creates a better feeling of the product. Thermoplastic material is molded around an insert piece or pieces placed in the plastic injection molding cavity, resulting in a single strongly bonded, integrated assembly, with the insert or inserts encapsulated by the plastic.Thermoplastic Injection Molding

Available Materials
Available Finishes
For rapid design molds, customers can receive T1 samples off a steel tool in as fast as 10 business days. Customers own the core and cavity inserts and we use factory-owned, interchangeable mold base inserts. Aluminum, S50C, P20, and NAK80 tool inserts are available as well as the Master Unit Die (MUD) quick-change system. Side actions are created with hand pick out inserts.
For production tooling, we produce stand-alone tools, ultimately owned by the customer. P20, H13, S7, NAK80, and SS420 insert steel is available as well as family & multi-cavity tools.
We will polish the mold to make the injected parts smooth enough, without obvious tooling marks.

Injection Molding Applications
With rapid injection molding, we can produce parts within 1-2 weeks using material the same as requested end products, which will outperform the 3D printed or CNC machined prototypes. CNC machining can be applied to make high-quality tools from aluminum 7075-T6 for injection molding, the lifespan, depending on geometry of the design, lasts 1,000-5,000 parts. Injection molding is the best choice for mass production the end products can be made using the exact material that will eventually be produced before the mass production.
