Precision 注塑成型 Services Worldwide
SSP Precision delivers high-performance custom injection molded parts — from rapid prototyping to full-scale production — with 50+ materials, 25+ surface finishes, and global delivery.
What Is Injection Molding?
Injection molding is the world's most efficient manufacturing process for producing high-volume, dimensionally accurate plastic parts. Molten plastic material is injected under high pressure into a precision-engineered steel mold cavity, where it cools and solidifies into the desired shape — repeatedly, with consistent quality.
At SSP Precision, we have mastered this technology across 15+ years of manufacturing, serving clients in automotive, medical devices, electronics, consumer goods, and industrial sectors — shipping from our facility in China to over 30 countries worldwide.

SSP's Injection Molding Process
Our end-to-end injection molding workflow is engineered for precision, repeatability, and speed — from design review to finished part delivery anywhere in the world.
Design & DFM Review
Our engineers analyze your CAD files for moldability — wall thickness, draft angles, undercuts — and provide a Design for Manufacturability report.
Mold Design & Tooling
Precision P20 or H13 steel molds are CNC-machined and EDM-finished to ±0.005mm accuracy. T1 samples within 7–15 days.
Material Selection
We help you choose from 50+ engineering-grade resins — ABS, PC, PA66, POM, PEEK, TPE, LSR — matched to your strength, chemical, and thermal requirements.
Injection & Molding
Molten resin is injected at precise pressures (500–2000 bar) and temperatures into the mold. Cycle times range from 5 to 120 seconds depending on part geometry.
Cooling & Ejection
Conformal cooling channels maintain optimal mold temperature. Parts are ejected cleanly and consistently once solidified to the correct dimensions.
Quality Inspection
CMM measurement, visual inspection, and functional testing ensure every batch meets your drawing tolerances and quality standards before shipping.
Post-Processing & Finishing
Parts receive surface finishing, painting, plating, pad printing, or assembly as required — providing a complete, production-ready solution.
Packaging & Global Delivery
Parts are carefully packaged and shipped worldwide via air or sea freight. Full documentation including COC, MSDS, and material certs included.
The Injection Molding Cycle — Visualized
A detailed cross-section of every stage in the injection molding cycle, from raw resin to finished part — the process SSP Precision executes daily for clients worldwide.
Types of Injection Molding We Offer
From standard thermoplastics to liquid silicone and multi-component parts, SSP Precision covers the full spectrum of injection molding technologies for global clients.
Thermoplastic Injection Molding
The most common process — ideal for ABS, PC, PP, PA, POM, and dozens of other engineering resins. High volume, low cost per part, excellent dimensional stability.
LSR / Liquid Silicone Injection Molding
Two-component liquid silicone is injected at low temperature into a heated mold — ideal for medical-grade seals, gaskets, baby products, and wearables requiring biocompatibility.
Overmolding
A second material (often TPE or silicone) is molded over a substrate part, creating soft-touch grips, bi-color products, sealed assemblies, and improved ergonomics.
插入成型
Metal inserts, threaded nuts, or electrical contacts are placed in the mold before injection — encapsulated in plastic for strong, permanent integration in a single operation.
Gas-Assisted Injection Molding
Nitrogen gas is injected to create hollow channels inside thick-walled parts, reducing weight, eliminating sink marks, and achieving complex internal geometries.
Two-Shot (2K) Molding
Two different materials or colors are molded in sequence in a single mold — producing complex multi-material parts without secondary assembly, at high efficiency.
Micro Injection Molding
Designed for miniature precision parts weighing as little as 0.01g — used in medical devices, micro-optics, and microelectronics. Tolerances down to ±0.005mm.
Structural Foam Molding
A blowing agent creates a cellular foam core within a solid skin — producing lightweight, rigid structural parts with excellent strength-to-weight ratios for industrial applications.
Thermoset Injection Molding
Epoxy, phenolic, and BMC materials are permanently cross-linked during molding — ideal for electrical components, heat-resistant housings, and parts requiring dimensional stability at high temperatures.
