Properties: GPPS (optical clarity, brittle); HIPS (High Impact grade).
Processes: High-speed cycle processing, Standard Injection.
Industries: Consumer Goods, Medical Disposables.
Applications: Petri dishes, transparent protective covers, appliance internal structures, laboratory labware.
ABS (Acrylonitrile Butadiene Styrene)
The versatile engineering workhorse for impact-resistant housings, offering the ideal substrate for premium Class-A surface finishes and electroplating.
Properties: Exceptional impact resistance, high dimensional stability, and excellent secondary finishing (electroplating/painting) compatibility.
Processes: Standard Injection, Hard Substrate Overmolding.
Industries: Automotive Tier-1, Consumer Electronics, Office Equipment.
Applications: Center console panels, electronic enclosures, power tool handles (base substrate).
Processing Guidelines for Commodity Resins
Our commodity plastics injection molding library includes a wide range of injection molding materials. Whether you need ABS plastic injection molding for enclosures or polypropylene injection molding for living hinges, we guarantee consistent quality at scale.
| Material | Avg. Mold Shrinkage (%) | Melt Temp (C) | Mold Temp (C) | Drying Required? |
|---|---|---|---|---|
| PP (Polypropylene) | 1.0 - 2.5% | 200 - 280 | 20 - 80 | No |
| HDPE | 1.5 - 3.0% | 200 - 280 | 10 - 60 | No |
| ABS | 0.4 - 0.7% | 210 - 270 | 40 - 80 | Yes (Recommended) |
| HIPS (Polystyrene) | 0.4 - 0.7% | 180 - 260 | 10 - 50 | No |
The Jucheng Advantage for High-Volume Production
In-House Multi-Cavity Tooling
We leverage our 25+ 5-axis CNC machines to build high-cavitation molds (up to 64 cavities) in-house, significantly reducing the per-part cost for high-volume commodity orders.
Blazing Fast Cycle Times
Our 35+ modern injection presses (50T to 650T) are equipped with high-speed hydraulics and robotic automation to minimize cycle times and maximize throughput.
Certified Quality Control
Operating under IATF 16949 and ISO 13485 standards, we utilize Zeiss CMM inspection to ensure consistent dimensions across every part, even in million-unit production runs.
