Here is an introduction to the differences between vertical and horizontal injection molding machines. In vertical machines, the mold opens and closes in the vertical direction, and the installation footprint is often about half that of horizontal machines, resulting in approximately double the productivity per floor area. On the other hand, horizontal machines open and close the mold in the horizontal direction, making it easy to arrange multiple machines in parallel and collect molded products on a conveyor. **Features of Vertical Machines:** - Easier to perform insert molding - Advantageous for precision molding - Easier to accommodate complex and sophisticated automation - Easier to achieve uniformity in resin flow within the mold and temperature distribution of the mold - Capable of using "removable molds" that can be produced at a low cost due to their simple structure *For more details, please refer to the related link page or feel free to contact us.*

The "Polishing Less Roll Injection Molding Machine" is a molding machine that mixes two-component silicone rubber and injects it into a cylindrical mold with an insert core. It was developed with the aim of manufacturing silicone rubber rollers. It is designed and manufactured to match the specifications of the user's molded products while making the most of our existing units. We can also design and manufacture new models to meet your specifications. 【Features】 ■ The plunger-type injection device is specifically designed for LIM machines. Supports a range from small to large capacities. ■ The mixing of the two components adopts a proven static mixer method. ■ Upward injection is used to minimize air entrapment. ■ The nozzle employs a shut-off type. ■ The injection cylinder is arranged vertically for space-saving. *For more details, please download the PDF or feel free to contact us.
