Plasticizing screw
Professional screw design makes the melting density uniform and ensures the consistency of physical properties and Gram weight of injection molded products.
|
|
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. |
|
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.

– OTHER SYSTEMS –
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. |
