The "Integrated Molding from the Start" by Kawabe Trading Co. is a technology that allows for the molding of various colors and different types of resins all at once. Traditionally, the common method involved molding several colors and types of materials separately and then combining them. However, with this technology, significant time savings and cost reductions can be achieved in the assembly and processing stages. 【Features】 ■ Time reduction rate: Approximately 50% ■ Cost reduction: Approximately 20% ■ Capable of molding multiple colors and different types of resins at once ■ Achieves significant time savings and cost reductions For more details, please refer to the catalog or feel free to contact us.

Rotary molding creates multiple surfaces for the lower mold in relation to one surface of the upper mold. In "insert molding," an insert fitting is placed into the lower mold at the front, and molding is performed at the back while rotating the table. Since the lower mold rotates horizontally and does not move up and down, the insert operation can be performed safely and reliably. The insert and product removal operations can be carried out simultaneously at a different position from the molding stage while the molding operation is ongoing. 【Advantages】 ■ Safe and reliable insert operation ■ Improved work efficiency ■ Significant reduction in molding cycle time ■ Low-cost production is possible For more details, please contact us.

We would like to introduce our technical research on "Outsert Technology." Battery packs for video cameras and other devices require terminals for charging and discharging the batteries. These terminals are very small and prone to deformation. We have designed and developed equipment to automatically press these small terminals, achieving high quality and low cost in mass production. This includes an 8-stage rotary automatic terminal press and a semi-automatic press for round-shaped terminals (with bending functionality). For more details, please contact us.

In "ultra-thin wall molding," resin is injected instantaneously during filling to prevent short shots, sink marks, and weld lines, while also controlling warpage. By reducing wall thickness, lightweight and high-cycle production becomes possible. In "two-material thin wall molded products," we combined single-color ultra-thin wall molding technology with appearance two-material molding technology. To fill the second material, the surface of the first material's resin is filled, and issues such as warpage, sink marks, and burrs are controlled through molding techniques. 【Features】 - No short shots, sink marks, or weld lines - Further control of warpage - Lightweight and high-cycle production possible For more details, please contact us.

We would like to introduce the technical research on "Weldless Forming Technology." With "Weldless Forming Technology," it is possible to eliminate weld generation through the method used. Additionally, it is also possible to control the position of the weld and make it less noticeable. Both are technologies for controlling metallic orientation. For more details, please contact us.

At Kawabe Shokai Co., Ltd., we have introduced a two-color molding machine that shapes two types of materials at once. There are mainly two methods: one is the two-color molding method using two different colors, and the other is the two-material molding method using different types of resin. If you want to reduce processing in the assembly process and cut costs, or if you want to add functions to your products such as grip feel and transparency, please contact us. Additionally, we also propose multi-color molding (three materials) as an application of two-color molding, and decorative plating is also possible. 【Features】 ■ Molds two types of materials at once ■ Cost reduction is possible ■ Reduction of processing in the assembly process ■ Multi-color molding (three materials) is also possible ■ Finished products can be retrieved in one shot cycle For more details, please contact us.

"Natural Beauty Plastic Molding" is a plastic molding process that does not require painting. By eliminating the need for painting, it reduces the time and cost associated with plastic painting. It results in a beautiful finish without weld lines. It is possible to produce a metallic appearance by incorporating aluminum or pearl into the resin material, maintaining the sparkling effect right from the molding process. Additionally, it is an environmentally friendly molding method. 【Features】 ■ No painting required ■ Reduces time spent on painting ■ Cost reduction ■ Eco-friendly *For more details, please refer to the catalog or feel free to contact us.
