Are you facing any of the following issues with outsourced plastic product manufacturing? ■ It takes a long time to deliver ■ Defective products are appearing at a certain frequency from the molded items ■ Material loss is occurring due to defective products and scraps If you have such concerns, mold design using flow analysis may provide a solution. Typically, mold designers predict the flow of resin based on their past experiences and design the molds accordingly. However, it is rare for things to go well on the first try based solely on experience and intuition, and several prototypes are often necessary. Kowa Electric Industry has over 80 years of experience in plastic molding for social infrastructure products and has created more than 700 molds using flow analysis. By adopting flow analysis technology, we can reduce the number of prototypes and achieve shorter delivery times. Additionally, by visualizing the flow of resin, we can reduce manufacturing losses while simultaneously improving quality and reducing defective products. If you are struggling with quality, material loss, or delivery times for outsourced plastic products, please feel free to consult with us.

The purposes of prototyping plastic products vary. Typical examples include: 1. I want to conduct prototyping to confirm the properties of new materials. 2. I want to prototype to verify quality, functionality, and design shape. 3. I want to prototype to see market reactions. 4. I want to conduct prototyping with the premise of mass production. [Response Examples] 1. Depending on the type of new material, we will use appropriate molding methods and keep the shape to the minimum necessary for performance verification, focusing on performance testing. 2 and 3. If confirming design shape, we can choose materials without restrictions, including 3D printing or vacuum casting using silicone rubber molds. For molds, we can use simple molds that are relatively inexpensive to manufacture, as well as wooden or resin molds. Naturally, machining is also an option. 4. Since this is prototyping before mass production, it serves as a final adjustment to mold under the same conditions and molding methods as mass production. Our company was founded on plastic molding and has responded to various customer requests. With a wide network of partner companies, we can accommodate various molding methods and assist with your prototyping needs. Please feel free to consult with us.
