New product "Spiral Water Pipe Sprubush - P Size Specification Type" now on sale and receiving great reviews!!

パンチ工業 パンチ工業
The "Spiral Water Pipe Sprue Bush" efficiently regulates the temperature of the sprue section by circulating a cooling medium through the water pipe, resulting in significant improvements in injection molding production, such as "stabilization of product quality," "reduction of cooling time," and "decrease in power consumption." In response to customer demands for the ability to freely specify the sprue diameter, we have launched the 'P Dimension Specification Type'!

Injection molding / temperature control / spiral water pipe sprue bush

Plastic injection molding direct temperature control to the sprue section, cooling time for molding tests reduced by 60%.

The spiral water pipe sprue bush is an item that enables temperature control in the challenging sprue section of plastic injection molding. Through metal light shaping and composite processing, a highly efficient spiral water pipe is integrated into the sprue bush, allowing for direct temperature control of the sprue section. This contributes to reducing cooling time in injection molding, increasing cycle speed, stabilizing the quality of molded products, and ultimately lowering total costs.

Aluminum prototype: Lost wax casting sand mold layered 3D printer prototype.

  • NEW
  • COMPANY

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

[Cast Iron Crack] We will repair cracks in metal products without applying heat.

  • NEW
  • COMPANY

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
