KR Series Plastic Injection Molding Machine
KR Series Plastic Injection Molding Machine
Plastic Injection Molding Machine Feature
- Vertical mold clamp with horizontal extruder with long closing and opening stroke, ideal for extrusion of large work pieces.
- Extra heavy structure and large mold capacity along with simple and easy-to-use layout.
- Horizontal extruder can be raised or lowered using hydraulic screws for fast, accurate positioning.
- There are few restrictions on the dimensions of molds or mold lines, and the range of applications is very broad.
- The platen uses self-lubricated axles which require no further lubrication, for smooth, easy movement and super-long useful life.
- Special functions for certain products can also be programmed, including strong clamping force, small extrusion quantities, faster extrusion rates, multiple die-sets, mold ventilation, mold vacuum and other operations.
- Other functions include insertion and cyclic finishing with a slide platen or rotary plate as needed.
