What is Injection Molding?
Injection molding is a precise and efficient process for producing complex plastic parts in large volumes. The method involves injecting molten plastic into a mold cavity, where it cools and solidifies into the desired shape.
At SSPrecision, we design and build high-performance injection molds and provide custom plastic injection molding services for clients worldwide. Our solutions ensure tight tolerances, smooth finishes, and consistent part quality — ideal for demanding industries such as automotive, electronics, and consumer goods.
Our Injection Molding Process
Our ISO-certified manufacturing process ensures accuracy, repeatability, and long mold life at every stage.
1. Design & Engineering Review – We start by reviewing your part drawings and 3D models, performing mold flow analysis to optimize gate location, wall thickness, and cooling.
2. Mold Design & Material Selection – Using software like UG, SolidWorks, and AutoCAD, our engineers design the mold structure and select durable steels (P20, H13, 718H, S136) suitable for production conditions.
3. CNC Machining & EDM Tooling – Mold components are precisely manufactured using multi-axis CNC machining and wire-cut EDM with accuracy up to ±0.002mm.
4. Mold Assembly & Polishing – Skilled technicians assemble, polish, and fine-tune each mold for optimal injection performance and product surface quality.
5. Trial Run & Part Sampling – We conduct T0 and T1 sample runs to verify mold performance, dimensions, and cycle time. Adjustments are made before final approval.
6. Mass Production & Quality Control – Once approved, molds are used for full-scale production with strict inspection of dimensions, color, and surface finish to meet customer specifications.

Types of SSP's Injection molding services
Micro molding
Micro Injection Molding specializes in producing ultra-precise, miniature plastic parts with tolerances as tight as 0.001 inches (0.025 mm).
Green Molding
Produces sustainable plastic components using biodegradable materials like PLA and PHA. Combines traditional molding precision with eco-friendly material science, delivering high-performance parts.
LSR molding
Liquid Silicone Rubber (LSR) Molding produces high-precision, flexible silicone parts with superior heat resistance and biocompatibility.
Multi-Cavity Molding for High-Volume Production
Multi-cavity molding is a precise manufacturing process that produces numerous identical plastic components simultaneously with one copied cavities mold. We are ISO 13485 and IATF 16949-certified and maximize high-volume manufacturing of medical, automotive, and electronic components with 85% lower cycle times and zero defects.
Multi-Shot & Two-Shot Plastic Molding
Two-shot and multi-shot molding are advanced technologies in which blends of different materials are fused together in one step to form integrated parts with enhanced bonding and performance. Rotating core and timed injection cycle precision mold design experience produces flawless material joining (e.g., TPE-to-ABS or LSR-to-PC) at ±0.02mm accuracies. Temperature (±1°C) and pressure are controlled to avoid delamination, in reaching medical-grade (ISO 13485) and automotive (IATF 16949) standards
Over-molding & Insert Molding
Over-molding and insert molding are sophisticated injection molding technologies with two or more materials or pre-molded inserts integrated into a consolidated part. Due to our tooling design precision and process optimization capabilities, we achieve flawless substrate material bonding of metals, plastics, and elastomers with ±0.03mm dimensional tolerances. temperature-controlled systems (±1.5°C), we adhere to medical-grade (ISO 13485) and automotive (IATF 16949) compliant.
