Plastic Materials We Machining & Molding

Plastics are versatile materials used across industries for their strength, flexibility, and chemical resistance. The list below shows the common plastics we custom process through injection molding, CNC machining, casting, and compression molding. If you don’t see the material you need, please contact us for a tailored solution.

ABS

(Acrylonitrile Butadiene Styrene)

Impact-resistant plastic with smooth finish. Easy to machine and paint. For automotive, appliances, and electronics.

PP

(Polypropylene)

Lightweight, chemical-resistant, FDA-approved for food contact. Low low-temp impact strength. Used for containers, bumpers, and labware.

PA/Nylon

Polyamide

Strong, wear-resistant with natural lubricity. Absorbs moisture—stability varies with humidity. Ideal for gears, bearings, and under-hood parts.

PE

(Polyethylene)

Chemically inert, low-cost general-purpose plastic. Good electrical insulator. Used for packaging films and chemical tanks.

PS

(Polystyrene)

Rigid and transparent but brittle. Low-cost and easy to fabricate. Common in disposable cups, CD cases, and packaging trays.

PVC

(Polyvinyl Chloride)

Versatile—rigid or flexible depending on additives. Flame-retardant and chemical-resistant. Found in pipes, cable insulation, and medical tubing.

PC

(Polycarbonate)

High-impact transparent plastic. Resists breakage and handles temperatures from -40°C to 120°C. Common in safety shields, headlamp lenses, and medical devices.

POM/Acetal

(Polyoxymethylene)

Rigid, low-friction plastic with metal-like strength. Excellent dimensional stability. Used for precision gears, fasteners, and sliding components.

PMMA/Acrylic

(Polymethyl Methacrylate)

Crystal-clear alternative to glass with excellent weatherability. More brittle than PC. Popular for signage, light covers, and display fixtures.

PC/ABS

(PC/ABS Alloy)

Alloy combining PC’s strength with ABS’s processability. Better heat resistance than ABS alone. Used for laptop housings and power tool bodies.

LDPE

(Low-Density Polyethylene)

Soft, flexible, and transparent. Excellent for squeeze bottles and stretch films. Lower strength than HDPE.

HDPE

(High-Density Polyethylene)

Stiff, strong, and moisture-resistant. Opaque white appearance. Used for milk jugs, chemical drums, and piping systems.

PTFE/Teflon

(Polytetrafluoroethylene)

Extreme chemical resistance and lowest friction of any plastic. Stable from -200°C to 260°C. Used for seals, non-stick coatings, and chemical linings.

UHMWPE

(Ultra-High Molecular Weight Polyethylene)

Ultra wear- and impact-resistant. Self-lubricating with low friction. Hard to process; needs special methods. For conveyor guides, wear strips, docks.

MC Nylon

(Cast Nylon)

Higher molecular weight than injection-grade nylon. Superior wear resistance for large parts. Used for industrial rollers, bushings, and conveyor components.

FAQs About Plastic Material Parts

Don't get your answer? Let’s jiangzhi answer for you!

My part warps or shows sink marks. How should I choose the material?

Use low-shrinkage, good-flow materials and keep wall thickness uniform. High-shrinkage plastics (like PP, PA) need thinner walls, while high-filled PC may require thicker walls.

I need a high-strength or impact-resistant part. Which plastics are suitable?

PC, PC/ABS, and POM offer high strength and toughness, ideal for load-bearing or impact-prone components. Glass-fiber reinforced grades can further enhance performance.

Can I make transparent plastic parts?

Yes, PMMA and PC are commonly used for transparent parts. Use optical-grade materials and control processing conditions to avoid bubbles or haziness.

My product is often exposed to high temperatures. Which materials should I choose?

Use engineering plastics like PA, PC, or POM, which maintain strength and shape at elevated temperatures without deforming or losing performance.

What materials resist moisture and stay dimensionally stable?

POM, PTFE, HDPE, and PP have low water absorption and maintain dimensional stability. Avoid high-absorption plastics (like standard PA) to prevent swelling or deformation.
