One of the World's Largest Injection Molding Machine Manufacturers

10+ Stages

The build starts with the machine frame: the structural backbone of every injection molding machine. Heavy-duty I-beam steel is cut, welded, and precision-levelled to form a high-rigidity base that absorbs clamping forces and supports all moving assemblies. Chen Hsong's frame design is reinforced by 50% over the industry standard, with a lower centre of gravity for vibration-free high-speed operation. Linear guide rails are installed at this stage to ensure long-term positional accuracy.

40+ Workshops

The clamping unit is the structural heart of the machine. Platens and toggle links are cast from high-grade ductile iron in Chen Hsong's own foundry, then precision-machined on CNC centres. Tie bars are manufactured and chrome-plated in-house. Toggle pins, bushings, and the complete locking mechanism are produced and assembled to tight tolerances. Chen Hsong's patented circular platen design distributes clamping force more evenly than conventional rectangular platens, reducing platen deformation by 25% under equivalent loads and extending mould life.

30+ Processes

The injection unit converts raw plastic pellets into precision-moulded parts. Barrels are bored from solid steel billets. Screws are manufactured, then nitrided and chrome-plated for wear resistance and corrosion protection. Nozzles are machined to exact tolerances. The complete plasticising assembly, including the hydraulic motor, screw drive, and barrel heater bands, is built and tested as an integrated unit. Shot-to-shot weight repeatability of less than ±0.25% is verified before the unit leaves the production line.

30+ Steps

The power behind every machine movement. Hydraulic manifold blocks are precision-machined and assembled with servo motors, proportional valves, and internal gear pumps. Chen Hsong's proprietary Precision Hydraulics™ system achieves movement repeatability of approximately 0.05% on critical axes. For all-electric and hybrid models, servo drive cabinets are assembled and integrated at this stage. The proprietary Ai-11 or SPS3300 controller is installed, wired, and calibrated. Chen Hsong is one of the few injection molding machine manufacturers that develops its own controllers in-house.

10+ Processes

All major assemblies converge on the final assembly line, where the clamping unit, injection unit, hydraulic system, and controller are integrated onto the machine frame. Safety guards and enclosures are fabricated from sheet metal, painted or powder-coated, and fitted. Every machine undergoes full commissioning, including dry-cycle testing, injection trials, and comprehensive quality inspection before it is cleared for dispatch.
