PET Injection Molding Machines (Jars & Cosmetic Bottle Preforms 160–480T)

1.A large L/D ratio screw with a reinforced mix-cutting section as a standard configuration is used to ensure even color mixing, less plasticizing back pressure, and higher plasticizing speed;
2.The screw assembly is made from imported steel by special heat treatment to prevent products from silver streaks, whitening, dark spots, high acetaldehyde (AA) and other defects, thus greatly improving the plasticizing quality;
3.The imported bearing and oil motor with higher power over the standard model result in low practical plasticizing pressure, a light load, stable plastic melt density, and easily adjustable back pressure;

Plasticizing Screw

The professional design of screw assembly ensures uniform plastic melt density and repeatable physics and weight of products
The screws’ compression ratio and L/D ratio are specifically designed to fully cut and mix raw materials and to minimize the discrepancy between the set temperature and the actual internal temperature during plasticization .

Screw Tip Assembly

High-hardness plated screw tip assembly makes the residue easy to clean, the products less black spots and impurities, and the screw more corrosion-resistant.
The screw tip assembly is made of alloy to ensure durability and precise non-return control.

Centering Bearing for Injection Table

The unique injection structure with one extra centering bearing on the basis of standard positioning bearing , enhances the positioning of plasticizing, reduces the radial runout of the screw during plasticizing, further, improves the resistance of screw component & the durability of bearing.

Linear Guide Clamping Toggles
The injection position achieves a repeatable accuracy of up to 0.1mm. (Tested under standard conditions in the factory)
The injection table has linear guides with a thickened frame, allowing minimum movement resistance and high-speed injection response.		 Strengthened three molding platens, with the center-force design and finite element force analysis, optimize the mechanical curve of clamping toggles to enhance the speed and precision of mold opening and closing.
Clamping Unit Large-Diameter Oil Circuit
Strictly check the parallelism between the fixed and moving platen and the withstand of clamping force consistency for four tie bars.
We rigorously test the parallelism of the movable and fixed platens and the uniformity of clamping force on four tie bars.		 Adopt a large-diameter oil circuit and a control method with low internal resistance to improve the response tempo and repeat accuracy of injection.
