Yamato Chemical Industry Co., Ltd. is a manufacturer specializing in industrial plastics. We possess three types of molding methods (blow molding, injection molding, and vacuum molding) and have in-house 3D printers, enabling us to provide a one-stop service. As a result, we can accommodate orders and deliveries on the same day at the shortest possible notice. Recently, in response to customer requests, we have completed the prototype development of blow molding using fluororesin (ETFE). We are currently preparing for mass production. Fluororesin (ETFE) has one of the highest levels of chemical resistance among all resins, as well as excellent heat resistance, electrical properties, and weather resistance. We have successfully achieved blow molding with this material. Blow molding allows for significantly reduced material loss compared to machined products, enabling dramatic cost reductions. Cost reductions of 1/10 to 1/20 are possible. If you contact us, we will provide the best proposal tailored to your needs. *For more details, please download the PDF or contact us.

• Blow Molding Machine

Until now, 3D printers could only create models for display, but by incorporating carbon, we have increased strength, allowing parts to be used. Products and jigs with strength greater than mass-produced items can be made without molds. We now have a three-machine system in conjunction with conventional machines. 【Features】 ■ No molds required, suitable for small lots ■ Strength greater than mass-produced items ■ Practical use possible, not just models *For more details, please refer to the PDF document or feel free to contact us.

• Processing Contract

We received a request from our customer to deliver precision parts to automotive manufacturers without causing any dents or collapses while maintaining their shape. Additionally, they want to maximize the number of parts transported to improve transportation efficiency. In response, our company has produced a "Tray for Transporting Precision Parts." Considering the need for strength, we opted for a double-structured tray made through blow molding. (Injection molding has high mold costs, and vacuum forming lacks strength.) 【Production Overview】 ■ Material: Polyethylene (HDPE) / Polypropylene (PP) and others ■ Dimensions: 750mm (H) x 500mm (W) x 100mm (MAX dimensions) ■ Quantity: Capable of handling small lots ■ Delivery Time: Natural color (original color) / black color in as little as 2-3 days (other colors to be discussed separately) ■ Purpose: Container for transporting precision parts ■ Molding: Hollow molding ■ Processes (Technology): Design, drafting, estimation, prototyping, mass production ■ Scope of Support: From prototype development to mass production *For more details, please refer to the related link page or feel free to contact us.

The conventional product is made of steel pipes, but we would like to create a resin protective tube that complies with European standards. We would like to request production support to accommodate various sizes and expand the range of variations. There are also molded products with special shapes, and we would like to complete the series as moldable. This is a request from our customer. In response, our company has produced the "Wire Cable Protective Tube." We have designed the mold structure to match the lot size, reducing mold costs with multi-cavity molds and interchangeable block molds. 【Production Overview】 ■ Material: Polyethylene (HDPE) / Polypropylene (PP) and others ■ Dimensions: Φ150 x 500L (MAX dimensions) ■ Quantity: Small lot support available ■ Delivery time: 7 days after order ■ Application: Wire protective tube (protection of concrete structures such as bridges, LNG tanks, etc.) ■ Molding: Hollow molding ■ Process (Technology): Design, drafting, estimation, prototyping, mass production ■ Support area: From prototype development to mass production *For more details, please refer to the related link page or feel free to contact us.

We received a request from a customer who wants to use colored pellet materials (UL-approved flame-retardant materials) for small-batch production of injection-molded products. They also want us to support model production and aluminum machining (considering die-casting products). In response, our company manufactures "various housing covers." We are making the best proposals by utilizing cost-saving measures for mold expenses, such as common molds and switch-type gate processing methods. We can accommodate everything from resin machining models to aluminum machined products. 【Production Overview】 ■ Materials: PA, PC, ABS, POM, PP, PE, etc. ■ Dimensions: Capable of molding sizes from 50 tons to 650 tons ■ Quantity: Small lot production available ■ Delivery Time: From 14 days after order confirmation ■ Applications: Various housing covers, component cases, functional parts, etc. ■ Molding: Injection molding ■ Processes (Technology): Design, drafting, estimation, model prototyping, mass production, painting, printing ■ Support Areas: From prototype development to mass production (including appearance painting, conductive painting, and silk printing) *For more details, please refer to the related link page or feel free to contact us.

Although it is blow molding, we would like to create that shape even if the processing is complex. Traditionally, we have been machining extruded products, but we want to reduce costs through blow molding. This was a request from our customer. In response, our company has produced the "Snow Damage Protection Cover" and "Salt Damage Repair Parts." The "Snow Damage Protection Cover" is processed using a 3D NC machining center (with no processing errors). The "Salt Damage Repair Parts" have become products with minimal distortion, even with a very thin diameter and large wall thickness. 【Features】 ■ Snow Damage Protection Cover - Processed using a 3D NC machining center - No processing errors ■ Salt Damage Repair Parts - Minimal distortion even with a very thin diameter and large wall thickness - Made with a specially developed resin not intended for blow molding *For more details, please refer to the related link page or feel free to contact us.

We received a request from a customer to produce molded products made from new materials that have never been used before, as well as complex hollow molded products. In response, our company manufactures "medical devices" and "resin molded parts for nursing care equipment." We are exploring whether we can stably produce molded products using unknown materials. We have a proven track record in three-dimensional curved processing and have smoothly transitioned to mass production. 【Production Overview】 ■ Materials: Urethane, acrylic, PC, nylon, Duracon, ABS, etc. ■ Dimensions: Within the capacity of engineering plastic molding machines (up to 700g per shot) ■ Quantity: Small lot production available ■ Delivery time: To be discussed separately ■ Applications: Various special analytical instruments, medical device components ■ Molding: Blow molding (supported by engineering plastic compatible machines and honeycomb dryers) ■ Processes (Technology): Design, drafting, estimation, prototyping, mass production (3D NC processing/NC lathe processing) ■ Supported areas: From prototype development to mass production *For more details, please refer to the related link page or feel free to contact us.

We will introduce product design to mass production, taking into account our actual processing and assembly. Through hearings regarding the products you are envisioning, we will share the required specifications and design images. Once the rough product concept is solidified, we will discuss the development approach and policy, and establish a development plan. After that, we will proceed through ordering, conceptual design, detailed design, and finally conduct final inspection and delivery. Products that pass inspection will be delivered according to your requests, including installation and setup work. 【Basic Flow】 ■ Meetings based on inquiries ■ Discussions and development planning ■ Ordering ■ Conceptual design ■ Detailed design ■ Prototyping ■ Manufacturing, assembly, and adjustment ■ Final inspection and delivery *For more details, please refer to the related links page or feel free to contact us.

Compared to other materials (expanded PP, PE, EPDM, 2-piece balls), it does not allow other products to catch up in terms of low cost, durability, and range of use. The mold cost is also low, and products can be manufactured in the desired shape.
