Advantages of StrongD Injection Molding Plastic Components
Efficient Mass Production
Injection molding has high efficiency and long mold life, which is suitable for medium and large batch order production, and the cost per piece is extremely low.
01
Precision Consistency
Through CNC processing of precision molds, high-precision control of ±0.01mm can be achieved.
02
Flexible Material Selection
Supports a variety of plastics and functional modified materials to meet various needs such as heat resistance, corrosion resistance, insulation, flame retardancy, elasticity, etc.
03
Exquisite Appearance
Can be directly injection molded to complete surface effects such as high gloss, matte, leather grain, mirror, etc.; and supports secondary processing such as painting and silk screen printing.
04
Strong Ability To Form Complex Structures
Can design complex structures, internal threads, buckles, thin walls, etc. to meet diverse product design needs.
05
Manufacturing Process of Injection Molding Plastic Components
The injection molding plastic relies on the design and manufacturing capabilities of precision molds. StrongD undertakes various injection mold projects:
StrongD mold types: single-cavity molds, multi-cavity molds, hot runner molds, two-color molds, rubber molds, etc.
Supports UG, Pro/E, SolidWorks, AutoCAD mold design, and fully considers the structure of demoulding slope, rib position design, wall thickness balance, cooling system optimization, etc.
Use high-precision processing equipment (CNC, mirror spark machine, wire cutting, etc.) to process high-quality steel molds
StrongD has a 50T~500T injection molding machine group, supporting two-color injection molding service and transparent injection molding from micro parts to large shells, and ensures quality by controlling parameters such as injection speed, holding pressure, cooling time, etc.
