Polystyrene (PS) Injection Molding Services
Custom GPPS & HIPS components with stable quality and reliable delivery.
Polystyrene Injection Molding
Polystyrene (PS) is widely used for consumer products, packaging, appliance interiors, toys, and general-purpose plastic parts. Kemal specializes in molding high-quality polystyrene (PS) parts, including both GPPS for clear, glossy components and HIPS for tougher, impact-resistant applications.
Our team supports you from DFM review to tooling and mass production, focusing on clean surface finish, consistent dimensions, and cost-effective cycle times. Send us your drawings or samples, and we’ll quickly confirm feasibility and provide a clear, competitive quote.

Why Choose Kemal for PS Injection Molding
PS-Focused Experience
We mold GPPS and HIPS parts for housings, covers, trays, and other PS components.
DFM Support
We check your PS part drawings for wall thickness, ribs, draft, and gating before making the tool.
Clear Capacity
Press range: 50–1,300 tons. Typical lead time: 2–4 weeks for tooling, 1–2 weeks for repeat orders.
Typical PS Parts We Mold
Polystyrene is widely used for light, cost-effective plastic components. Here are the typical PS parts we can mold for you:
• Consumer electronic housings
• Transparent covers and windows
• Packaging trays and inserts
• Appliance interior parts
• Toys and small decorative parts
• General-purpose PS plates and brackets
Comprehensive Plastic Part Services
We provide early-stage design for manufacturability (DFM) analysis to optimize wall thickness, draft angles, and gate placement. This helps identify risks upfront and reduces costly mold changes later.
From single- to multi-cavity and hot runner molds, we build tooling that matches your production needs. Steel selection and surface finishes ensure durability and precision over the mold’s lifetime.
We offer standard molding, insert molding, and overmolding options. Each run is monitored with scientific process controls and full batch traceability to guarantee consistent results.
Choose from painting, pad printing, laser marking, and UV coating. ABS is especially well-suited for surface finishes, making it ideal for branded housings and visible parts.
Every part goes through strict IQC, IPQC, and OQC processes. We provide dimensional reports and compliance documentation to meet international standards.
From sub-assemblies to custom packaging, we streamline the final steps before shipping. Global logistics support ensures your parts arrive efficiently and ready to use.
