Plastic injection molding is designed especially for the mass production of plastic parts by repeatedly using the same mold. Consistent color, structure, appearance is the features for injection molded parts. Hundreds of thousands of custom parts are produced by machines. The cost of per part decrease with higher quantity manufacturing runs.

Our Injection Molding Capabilities

We have 30+ injection molding machines from 80T to 470T that can produce common size injection molded parts. The tonnage calculation/clamping force is one of the key factors for quality and cost. It keeps the tooling closed during the injection process. The higher tonnage, the higher weight of tooling it can keep.

Plastic Material Property

2fprototypes provides various materials for your choice. Contact us to know which is right for you.

Polystyrene/PS and modified polystyrene/HIPS: 
Good fluidity for easier processing;
Good dimensional stability; Easier coloring;
High brittleness for poor shock resistance;
Can be scratched on the surface easily;
Poor acid resistance for crazing;

polymethyl methacrylate/PMMA/Acrylic:
Burning slowly;
High transparency;
Forming easily;
Scratching easily

Propylene - butadiene - styrene polymers/ABS:
The best electroplate ability among plastics;
The ingredient of butadiene improve the shock resistance greatly;
Good surface gloss;
Low shrinkage for reliable dimension;
Organic solvent intolerance, can be dissolved into emulsion when combining with ketone, ester, aldehyde, and chlorinated hydrocarbon

Polyamide/PA/Nylon - Crystalline plastics:
Good toughness;
Good wear resistance;
Good fatigue resistance;
Good self-lubrication;
Good self-extinguishment;
Good strength of extension;
High water absorption

Polyformaldehyde/POM - Crystalline plastics:
Comprehensive mechanical performance;
High rigidity and hardness; Excellent worn resistance and self-lubrication;
Organic solvent tolerance;
Low moisture that can maintain stable dimension;
Low acid resistance;
Low adhesiveness;

Polycarbonate/PC - Crystalline plastics:
The best plastic of shock resistance; Low forming shrinkage(0.05-0.7%) that the end-part is precise and the dimension is stable;
Burning slowly;

What Is Plastic Injection Molding

Plastic injection molding is one of the oldest manufacturing ways. Its capability of volume-production is still the popular choice of large custom manufacturing. Plastic injection molding is the process that plastic is squeezed into the mold and then be shaped. The basic principle may be simple, but it is a very complicated process in reality. Many factors can change or destroy the quality. The quality and consistency of the final parts require the right equipment and rich experiences.
 
The plastic injection molding machine is made of a hopper, injection ram, heating device, mold, ejector pin, etc. Generally, the injection molding machine works horizontally. When choosing suitable plastic pellets, they will be poured into the heating system by hopper. Plastic pellets can be melted down into moldable liquid by the heating device that is created by the frictional action of the screw. The plastic liquid will enter the mold cavity by way of the runner system and mold gate. The whole process is known as an injection. The plastic will be molded and cooled after injection. The mold opens and drops the molded part and is then ready for the next injection. Depending on the mold lifetime, the injection molding process will be repeated over and over until the job is completed or the mold needs to be replaced.

 

Basic process of injection molding - 2fprototypes


Step 1: Add plastic materials(pellets) into the hopper
Step 2: Pellets will be heated and melted down in the barrel
Step 3: The heated plastic is injected into the mold through the nozzle
Step 4: Plastic is allowed to cool and harden in the mold
Step 5: The mold opens and ejects the parts
