Welcome: Premium Machining Co., Ltd

Plastic Injection Molding

Rapid Injection Moulding

Rapid injection moulding allows us to make prototype injection moulded parts in a production thermoplastic resin. These parts may be used for final sign off, full functionality, fit testing and sales launches.

PREMIUM MACHINING is used to working on both low and medium volume production runs, depending on your project requirements. Through our many years of experience, we have achieved expertise in the rapid manufacture of aluminium and soft tool-steel tooling for production of high quality low to medium-volume parts. We can provide highly price-competitve solutions for low to medium-volume production requirements for your business.

· Production volumes of 50 to 100,000 parts can be produced at a reasonable cost per piece.

· All commercially available plastic materials are available.

We provide various kinds of surface finishing services, including plating, painting, silk screening, pad printing and hot stamp printing.


Design for Manufacture (DFM)

Mold Flow Analysis


Design for Manufacture is a helpful tool that we can provide to our customers to help minimise tooling costs and to help expedite the manufacturing process.

We will provide you with a detailed report that contains important information about your part design and highlights any potential problem areas.

In addressing design issues early on, the DFM helps to eliminate costly re-tooling or delays in the manufacturing process caused by a problematic part design.

We also have the ability to provide mould flow analysis, which, when combined with the DFM, can save you money and ensure production in a timely manner.

The Plastic Injection Molding Process

Once your plastic injection mold tools are ready, the molding process consists of the following basic steps:

Step 1. The plastic resin comes in raw pellets. These are dried to the right moisture content, and then if necessary they can be blended with pigments or master batch colorants.

Step 2. The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine will transport these pellets towards the mold.

Step 3. Within the barrel, the pellets are mixed and heated until fully molten, forming the liquid resin.

Step 4. The heated mold closes automatically and resin, under great pressure, is injected through a gate and into the mold cavity.

Step 5. The mold is cooled to solidify the part inside.

Step 6. The mold opens and the part is ejected to begin a new cycle.
