Injection molding machine for PET jars and cosmetic bottles (160-480T)

1. The screw has a large appearance ratio and a strong mixing section as a standard, which can guarantee a mixture of uniform color, lower back pressure from the fusion adhesive and admits faster fusion adhesive;
2. The plastification components are made of imported steel after a special heat treatment, which avoids undesirable phenomena such as silver silk, whitening, Black spots and acetaldehyde (AA) In injection molded products, And obviously improves plastification quality;
3. The fusion glue oil engine is larger than the standard machine, and the careful bearings of Germany are used at the same time. The real fusion glue pressure is low, The load is light, The fusion glue density is stable and the subsequent pressure is easy to adjust;

Plasticizing screw

Professional screw design makes the melting density uniform and ensures the consistency of physical properties and Gram weight of injection molded products.
The screw compression ratio and length diameter ratio are designed to ensure that the raw materials are completely cut and mixed in the plasticizing process., and the difference between the actual internal temperature and the set temperature is minimized.

Screw head assembly

The screw is made of high hardness material and electroplated, which makes the residual raw materials easy to clean, prevents black spots and variegated colors from injection molded products, and prevent the screw from being corroded.
The screw head assembly is made of alloy material to ensure durability and precise check control.

Lever centering

Single injection queue table structure: based on conventional bearing positioning, A fixed bearing is added to improve the positioning of the glue injection assembly.
This can effectively reduce the radial wear of the screw by melting the glue and improve the durability of the assembly and bearing of the screw by melting the glue load..

linear guide rail Introduction of automatic hinge
The injection position repetition accuracy is as high as 0.1 mm (use: tested under standard factory conditions)
The launch bridge adopts linear guide rail with thickened bracket to realize the lowest action resistance and support high-speed injection response.		 The three reinforced insoles are designed by central stress and analyzed by finite element method. The optimized mechanical curve of the hinge makes the rhythm of opening and closing the dice faster and more precise.
Mode clamping part Large diameter oil circuit
Strictly check the parallelism between the fixed template and the dynamic template and the consistency of the clamping force on the four lines. Adopt large diameter oil circuit control mode and low internal resistance to improve response beat and action repetition accuracy.
