Core Technology

New decoration techniques, created from a determined challenging spirit. Techniques that achieve assured quality and excellent cost performance by combining these in-house developed technologies. SANWA’s core technologies enable manufacturing with a high degree of freedom utilizing the refined sense of people.

1.Film Insert Molding

This is a manufacturing technology in which silk screen printed film is inserted into an injection mold, and then resin material is injected into the injection mold to create an integral mold with the film. This simultaneous decoration and molding process enables us to produce even such things as large parts and products with a complex curved shape. It is a technology of SANWA’s unique expertise, which enhances the technical capabilities in mold film printing, resin injection molding and other processes beginning with the design and manufacture of molds. The technology has the greatest potential for future manufacturing in the home appliances industry and automotive industry that requires a high level of design and sense of quality along with functionality.

2.High Added Value Painting

A special feature of SANWA is that we have advanced painting technology with high added value. We have various technologies including piano-black painting, clear painting, high-brilliance painting, and mask painting. Among these technologies, piano-black, which features a beautiful glossy and high-grade appearance, is a painting technology that has gained much attention in other areas besides the automotive industry. Since even the smallest amount of dust floating in the air can cause a defective product, we tightly control the process in conjunction with humidity control or such other factors.

3.Transparent Resin Decoration

Transparent resin decoration utilizes resin material with a clear texture. This is a technology with very strict conditions that does not allow foreign material within the resin or even the smallest defect. It is often used in two-color molding and SANWA takes pride in producing parts with beautiful transparency, therefore we conduct thorough quality control in a detailed manner. This technology enables us to provide products with even greater design and deeper expression.

With WELD

Without WELD

4.Weldless design

Sanwa’s weldless design is to create “weldless” visual on various shape. This is a technology to make the surface smooth without any disturbance of weldline. It can present the luxuorious attribute on the surface, especially on the high glossy visual. Our high technology to control the mould and conditions are the legacy of the accumulation of know-how up until today. This weldless will unlimit your imaginations for the ideal design.
