In order to ensure the implementation of the core value of "reliability and stability” among the A6 large tonnage machine family, we have refined and quantified the factors in terms of achieving improvement: With the normal process, the repeatability of product weight is up to 3‰. Available with clamping forces from 900 to 4,800 kN.
High cost-effective

High stability

High integration

Uniform-stress clamping technology
- Both the fixed and movable platen design adopts uniform-stress clamping technology, less platen deformation. Uniform-distribution of clamping force between mold and platen can prevent flash, parts missing and other undesirable defects, thus reducing he mold clamping force and extend the useful life of platens.
Optimized injection unit
UN90-480U1 series injection molding machine adopts single-carriage injection unit. Optimized injection unit not only improves its rigidity, but also ensures coaxiality between movement direction of injection unit and injection force, reducing the resistance and improving the injection stability and accuracy.
YIZUMI 3rd Generation Servo Energy-saving Technology
The 3rd generation energy-saving servo system is adopted, which has small moment of inertia, no bottom flow and lower energy consumption. The whole oil circuit is optimized in multiple ways, realizing the reduction in movement resistance and pressure flow loss during machine operation, to ensure lower power consumption of the complete machine.
MS control system
- The control unit adopts Cortex-A55 processor with scan time of 0.25ms, speedy response and accurate control.
- 1000 sets of mold data memory, USB port for extension of storage.
- 7+1 sections of PID temperature control supports switchover between type J and type K thermocouples. Automatic PID tuning improves the temperature control accuracy.

SKⅢ Series General Purpose Injection Molding Machine

Boasting enhanced efficiency and consistent energy savings, the SKⅢ series also excels in stability and user experience. Its design incorporates the interchangeability of the SK/A5 platform, thanks to continual optimization. Distinguished as the top choice among small to medium-sized injection molding machines, the SKⅢ series underscores a commitment to elevating the user journey. Available with clamping forces from 900 to 10,000 kN.

A5 Series Standard High-end Servo Injection Molding Machine

With larger specifications and faster response, wider processing range and lower repeated investment costs. Optimized injection units ensure precision and stability. Uniform-stress molding technology provides durability and reliability. Available with clamping forces from 600 to 26,000 kN.

Optimized clamping unit

1. The upgraded clamping unit can provide larger clamping force, better facilitating the molding of thin-wall and deep-cavity products. 2. Platen, tie bars and machine frame of better mechanical properties can better improve the rigidity of the whole machine and reduce deformation. 3. The rigidity of overall mold locking is increased by more than 25%.

Synchronous plasticizing

1. The plasticizing is synchronized with the cooling, mold opening and part picking, shorter cycle time. 2. PAC380K3 and above model are generally equipped with hydraulic synchronous plasticizing function, which shortens the product molding cycle.

Surface Planeness Testing

Rapid response Accurate detection.
