How We Injection Molding This PPS Part

When we inject-mold PPS parts, we need to be strict with drying – 130–150°C for 4 to 6 hours, and keep the melt temperature between 310°C and 340°C, mold temperature maintained at 130°C–150°C to ensure proper crystallization and dimensional stability. Injection pressure generally ranges from 80–120 MPa, while holding pressure is about 50–70% of the injection pressure to minimize shrinkage. Injection speed should be medium to high to avoid premature freezing, and back pressure is kept low at 0.3–0.8 MPa. Cooling time usually ranges from 15 seconds for this part. Due to PPS's high crystallinity, we use a hot runner system with precise temperature control for balanced filling in both cavities. Post-mold annealing at 150°C–200°C for 1–2 hours may be applied to relieve internal stress and optimize mechanical properties.

Advantages of PPS (Polyphenylene Sulfide) Material

PPS offers outstanding high-temperature resistance, with a continuous service temperature exceeding 200°C, making it ideal for demanding thermal environments. It provides excellent chemical resistance against acids, bases, and solvents, ensuring long-term durability. Its superior dimensional stability minimizes warpage and shrinkage, allowing for precision parts with tight tolerances. PPS is inherently flame retardant, achieving UL94 V-0 rating without additives. As a high-performance engineering plastic, it is an excellent metal replacement in applications requiring lightweight, corrosion-resistant, and high-strength components.

Our Workflow

A transparent, step-by-step process from design to delivery.

Stage 1: R&D SupportWe support customer R&D. Create the files or improve the design if needed (UG, SolidWorks, ProE, AutoCAD etc.)

Stage 2: Mold ProcessMold design (DFM report) → check/approve → approved → make mold → produce sample → sample confirmed → check final mold quality ready to export.

Stage 3: Sample ModificationIf the first sample does not satisfy the customer, we can modify the mold to meet customers' requirements.

Stage 4: Sample DeliveryProduce the customer's requested quantity, free shipping.

Stage 5: Final DeliveryDeliver goods by sea or by air; special requirements can be accommodated based on customer demands.
