サンエツ工業 List of Products and Services

"Vacuum forming" is a method of shaping sheet-like resin materials by heating them and pressing them against a mold, allowing for the creation of molds at a lower cost compared to other forming methods. Additionally, our company offers a wide range of services from sub-assembly to final packaging. With San-Etsu Industry's expertise in jig manufacturing technology, we design and produce assembly jigs and devices, enabling low-cost solutions by enhancing stable product creation and work efficiency. 【Vacuum Forming Features】 ■ Heating sheet-like resin materials and pressing them against a mold for shaping ■ Ability to create molds at a lower cost compared to other forming methods *For more details, please refer to the PDF materials or feel free to contact us.

At Sanetsu Industry, we handle everything from single prototype production to mass production for "plastic welding/adhesive assembly." "Plastic welding" allows for the strong joining of PP, PE, PVC parts, etc., by heating and melting round rods of the same material using a manual hand gun. "Adhesive assembly" enables solvent bonding of plastic processed products that can be bonded, such as acrylic, ABS, and PVC. 【Features】 ■ Support from single prototype production to mass production ■ Plastic welding - Strong joining is possible by heating and melting round rods of the same material using a manual hand gun ■ Adhesive assembly - Solvent bonding of plastic processed products that can be bonded, such as acrylic, ABS, and PVC *For more details, please refer to the PDF document or feel free to contact us.

"Ultrasonic welding" generates friction between two workpieces using ultrasonic waves, allowing them to be melted and joined instantly. Unlike adhesive or solvent bonding, it does not require drying time, making it suitable for mass production. If strength testing is necessary for ultrasonic welding, strength verification can be performed using a tensile testing machine. 【Features】 ■ Can melt and join instantly ■ Suitable for mass production ■ Caulking work on joint parts is also possible ■ Strength verification can be performed using a tensile testing machine ■ Full leak testing is conducted on parts that must not leak *For more details, please refer to the PDF document or feel free to contact us.

A "3D printer" refers to a machine that creates three-dimensional models by stacking sliced two-dimensional layers based on 3D CAD design data (STL data). Our company utilizes it for jigs for additional processing, contributing to increased productivity. In the case of prototypes, they can be created and evaluated in a short period and at low cost without the need for molds, leading to a reduction in product development lead time. 【Features】 ■ Prototypes - Can be created and evaluated in a short period and at low cost without the need for molds - Leads to a reduction in product development lead time ■ Jigs - Utilized for jigs for additional processing, improving productivity *For more details, please refer to the PDF materials or feel free to contact us.

• 3D Printer

At Sanetsu Industry, we have established a dedicated storage room for molding materials that is temperature-controlled 24 hours a day. For materials in use, we sew and seal the bags to prevent foreign matter contamination and manage the storage environment. All materials are dried at appropriate temperatures and times, and when necessary, placed in dryers equipped with dehumidification processes to prevent issues arising from resin thermal decomposition within the injection cylinder. We also manage the temperature and humidity of parts such as inserts, which are not molding materials, during storage. 【Features】 ■ Installation of a 24-hour temperature-controlled storage room for molding materials ■ Sewn and sealed bags for storage environment management ■ All materials dried at appropriate temperatures and times ■ Prevention of issues arising from resin thermal decomposition ■ Temperature and humidity management for parts such as inserts, in addition to molding materials *For more details, please refer to the PDF document or feel free to contact us.

• Other contract services

At Sanetsu Industrial, we have partner factories both domestically and internationally, and we can handle everything from mold design to manufacturing. We aim to create molds that are suitable for stable molding by selecting the appropriate mold structure according to product needs. Additionally, the molds, which are valuable assets for our customers, are stored in a climate-controlled environment within our factory. 【Features】 ■ Partner factories established both domestically and internationally ■ Capable of handling everything from mold design to manufacturing ■ Selection of appropriate mold structures based on product needs ■ Mold production that enables stable molding *For more details, please refer to the PDF document or feel free to contact us.

• Contract manufacturing

Both PVC and super engineering plastics are resins with excellent functionality, but there are not many factories involved in their molding. The reason for this is that the molding of both is highly challenging. At San-Etsu Industry, we can easily handle the molding of these materials using our unique methods. 【Features】 ■ PVC - Requires specialized molding machines due to gases generated during molding ■ Super Engineering Plastics - Plastic resin that can be used for long periods at temperatures above 150°C *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

At Sanetsu Industry, we always stock over 50 types of cutting processing materials, including plates (thickness 1mm to 100mm) and round bars (diameter 1mm to 100mm), to accommodate short delivery times. Inventory checks can be performed using our barcode management system. Additionally, through collaboration with various material manufacturers, we can quickly respond to stock shortages and special material requests. 【Features】 - Always stocked with over 50 types of cutting processing plates and round bars - Inventory checks possible with barcode management system - Collaboration with various material manufacturers - Quick response to stock shortages and special materials *For more details, please refer to the PDF document or feel free to contact us.

At Sanetsu Industries, we specialize in "additional processing" for molded products, such as when you want to make partial design changes or when dealing with round holes that are unsuitable for molded products. In additional processing for mass production lots, we can implement metal fabrication and automation of jigs, which allows for cost reduction and shorter delivery times. Additionally, for secondary processing tasks like Heli-Coil insertion and double-sided tape application, as well as shapes and burr finishing that are considered difficult with new equipment, we rely on skilled artisans with extensive experience and high-level techniques to complete the work by hand. 【Features】 ■ Specializes in additional processing for molded products, such as round holes that are unsuitable ■ Capable of consistent support from jig design to manufacturing and molded product processing ■ Implements metal fabrication and automation of jigs for additional processing in mass production lots ■ Finishing done by hand by skilled artisans with extensive experience and high-level techniques ■ Fusion of new equipment and skilled techniques *For more details, please refer to the PDF materials or feel free to contact us.
