In machining, we excel at processing resins such as plastics. Since 1995, we have introduced machining centers and 3D CAD/CAM to aim for product creation that satisfies our customers. Vacuum casting is a technique that uses silicone rubber instead of molds to pour resin in a vacuum and create replicas. Small lot alloy casting refers to a method that allows for the simple casting of alloys for small lot production, similar to die casting. Our Protect Design Service offers a "Product Design Service" that coordinates all elements from product planning to prototyping in collaboration with contracted designers, leading to mass production of the product.

The plastic materials compatible with Akagawa Giken's light curing technology are TSR-821 (tough type, PE/PP-like), TSR-829 (high transparency type, ABS-like), and TSR-883 (high rigidity and heat-resistant type). The ability to accommodate a sufficient number of devices for resins tailored to specific applications is considered the main feature. Additionally, in "medical light curing," Akagawa Giken is the only company collaborating to produce medical models using light curing. By having both gypsum models and light curing as tools commonly used for personal medical models, we can propose the optimal method tailored to the application. Since our establishment, we have accumulated 20 years of know-how in data processing for medical models, allowing us to accurately understand the requests from doctors.

Vacuum casting is a technique that uses silicone rubber instead of a mold, allowing resin to be poured in a vacuum to create replicas. The accuracy of the replicas is comparable to that of molds, and molds can be produced in a shorter time frame compared to traditional methods. Most parts that can be made through injection molding can also be replicated. It is also possible to insert and cast metal parts. We can accommodate sizes up to 1,200 x 1,200. For more details, please contact us.

The accuracy of the replicas is comparable to that of molds, and molds can be produced in a shorter lead time compared to traditional methods. Most parts that can be made through injection molding can also be replicated. It is also possible to insert metal components for casting. We can accommodate sizes up to 1,200 x 1,200. By performing surface treatment on the master, we can achieve a finish that is closer to product level and can also add color. For more details, please contact us.

It is recommended for molding that aims to reduce costs for small lots (approximately 50 to 1,000 pieces) and limited production items. The aluminum steel used for aluminum molds has a strength comparable to that of regular steel materials (such as S55C). With aluminum molds, the adoption of a common base for interchangeable systems significantly reduces the processing steps for the base. 【Processing Examples】 [Surface Treatments] ○ ABS material: Chrome plating + Ion plating ○ ABS material: Vapor deposition - Silver ○ ABS material: Metallic finish painting ○ ABS material: White glossy painting ○ PC material: Dyeing For more details, please contact us or download the catalog.

Customer Feedback on Arakawa Giken's Plastic Prototype Processing Service A certain vehicle manufacturer ⇒ Our company mainly manufactures parts related to vehicles, but we need prototype models as quickly as possible since we must conduct performance tests within a short timeframe. Arakawa Giken has always responded to our short delivery requests, which has been a great help. A gaming equipment manufacturer ⇒ I have heard that your company only does machining in-house, but it is convenient for us as an ordering party that you can handle all aspects of prototyping (casting, secondary processing, small lot molding, etc.) through your network. A mass production parts manufacturer ⇒ I think one of the advantages is that you can also handle mass production-related tasks, such as additional processing of molded products, not just prototype production. A tool manufacturer ⇒ The ability to process not only ABS materials but also heat-resistant and durable materials (such as PBT and nylon) is a key point. A mass production parts manufacturer ⇒ The technology cultivated over nearly 30 years of establishment is reflected in the machined products. A vehicle manufacturer ⇒ I believe you excel in Q.C.D (Quality, Cost, Delivery). If you are struggling with plastic prototype processing, please feel free to contact us!
