Injection Moulding Process:
Plastic injection moulding allows to produce large numbers of parts
with great accuracy and A quick cycle times from multi-cavity
tools. The process of injection mould involves a certain amount of
polymer materials being heated, melted, and injected into a mould
under high pressure. Further into the process, main units of the
injection moulding machine are:
- feed hopper;
- heated barrel;
- crew (known as the injection unit);
- clamp unit (which holds the mould together under the injection
pressures);
- ejection unit (which removes the part from the mould).

Amorphous vs Semi-crystalline Thermoplastics:
There are two types of thermoplastic materials that we commonly use
at Integrated Molding Solutions,
amorphous and semicrystalline. Amorphous thermoplastic material can
be highly transparent and
has good formability with a lower melting temperature range. While
amorphous thermoplastics have
poor chemical resistance, this provides an easier bond to other
materials using adhesives or solvents.
On the other hand, semicrystalline thermoplastic material has great
fatigue and stress cracking
resistance making it the perfect material for bearing and wear.
However, semicrystalline thermoplastic
material can have high chemical resistance and difficulty bonding
to other parts using adhesives or solvents.
Amorphous and Semi-crystalline thermoplastic material comparison
chart:
| Amorphous Thermoplastics | Semi-crystalline Thermoplastics |
| Soften over a wide temperature range | Sharp melting point |
| Good formability | Poor form ability |
| Transparency | Opaque |
| Poor chemical resistance | Good chemical resistance |
| Bonds well using adhesives or solvents | Difficult to bond using adhesives or solvents |
| Prone to stress cracking | Resistant to stress cracking |
| Poor fatigue resistance | Good fatigue resistance |
| Structural applications only | Good for bearing and wear |
| Acrylic, PC, ABS, PS | LDPE, HDPE, PP, PET |
When comparing plastic materials, use this plastic materials
comparison chart to identify which injection molding materials
will meet the product specifications. One of the many benefits of
working with a professional plastic fabrication company
is their knowledge of plastic material alloys, fillers, and
additives. Custom plastic injection molding materials can be
engineered
to meet required product properties that common plastic molding
materials cannot.
