Aesthetic Appeal. Introducing a transparent coating for plastics. Transparent plastics such as acrylic and polycarbonate tend to become cloudy and lose their clarity when machined. While acrylic can be polished to restore transparency, intricate shapes may not receive adequate polishing in all details. This is where transparent coating comes into play. It can be applied to materials such as polycarbonate, ABS, and PVC. How about using it for your company's planning and development models or for experiments and verifications with transparent devices? Being transparent can also enhance work efficiency in assembly jigs, making it versatile for various applications. Please feel free to consult us about realizing your ideas or any concerns you may have.

This is an introduction to a method for producing prototypes using mass production materials before mass production. We often receive inquiries from customers who want to prototype using the materials that will be used in mass production, wish to create products with a small amount of molded material, or want to keep initial costs down. We would like to propose two possible methods for this. ■ Simple Mold Forming ■ Machining from Blocks Simple mold forming involves creating a low-cost temporary mold by changing the structure, number of cavities, and materials of the mold. This method may allow for a faster turnaround than starting with a production mold. Regarding machining from blocks, the materials that can be used are limited, but we can create blocks through molding and then machine them into products. 【Plastics】 Examples of materials used: ABS V0, PC V0, PBT GF15%, PPS CF10% (Some molded materials may require provision by the customer.) Possible size: 250×250×55 *Please note that depending on the material, it may not be possible to create blocks for plastics. Prototype costs will be incurred, but it is also possible to test the feasibility of block molding. 【Rubber】 Available materials: General press-molded materials (Please provide materials.) Possible size: 100×100×50

This is an introduction to thermosetting plastic molding. If you have a source for thermoplastic requests but are looking for a source for thermosetting plastic, or if you are seeking advice for the first time, please feel free to consult with us. Our company is capable of handling various molding methods for thermosetting plastics as follows: 【Molding Methods】 ■ Compression Molding ■ Transfer Molding ■ Injection Molding ■ Epoxy Casting, Vacuum Epoxy Casting ■ Insert Molding Below are representative materials. 【Materials】 ■ Epoxy ■ Melamine ■ Phenolic ■ Urea ■ Unsaturated Polyester ■ Diallyl Phthalate Please consult with us first. 【What is Thermosetting Plastic?】 There are two types of plastics: thermosetting and thermoplastic. As the name suggests, thermosetting refers to materials that harden when heat is applied. Conversely, thermoplastic becomes soft when heat is applied and solidifies when cooled. A common analogy is that thermosetting is like cookies, while thermoplastic is like chocolate.

Introducing thermoplastic plastic molding. When it comes to mass production of plastics, injection molding is the way to go. Our company can handle molding not only for general plastics and engineering plastics but also for super engineering plastics like PEEK. Additionally, we offer integrated services including insert molding, two-color molding, as well as post-molding printing and plating. Please feel free to consult with us. 【What is super engineering plastic?】 It refers to materials with a continuous use temperature of over 150°C. Among them, PEEK has a continuous use temperature of 250°C, which limits the options for molding. 【What is two-color molding?】 It is a molding method that combines different resins or materials (e.g., plastic and elastomer) into a single unit. 【Our strengths】 Our company is also skilled in producing prototypes before molding. This allows us to handle everything from prototyping to mass production in a seamless manner, facilitating smooth communication regarding gaps and detailed discussions between the prototype and mass production stages.

Ah! It's the weekend today. If you find yourself in an emergency situation where you need parts urgently, such as missing necessary components for early next week or having overlooked an order, please contact us. Our site operates on weekends and holidays as well, so if materials are available and the processing machines have open slots, we can make "processing and shipping over the weekend" a reality. Depending on the materials, processing details, and quantities, we will do our best to accommodate your request with the best possible delivery time.

Introducing plastic grinding processing. Do you want to achieve dimensional accuracy in plate thickness but are concerned about machining marks (full back marks) in mechanical processing? Or do you have issues with wanting to improve dimensional accuracy beyond what you currently have? Our company can provide not only precision grinding of plastic plate thickness but also machining, allowing us to deliver finished products. 【Material Examples】 ■ Bakelite ■ PEEK ■ Glass epoxy We can also handle material procurement. 【Plate Thickness Accuracy】 ■ ±0.01 to ±0.05 The achievable accuracy varies depending on the material and size. *For more details on materials and sizes, please refer to the PDF catalog or feel free to contact us.

By consulting with us, you can save the effort of searching for suppliers and arranging meetings based on different manufacturing methods. Please feel free to reach out to us for a consultation.

This is an introduction to plastic welding for tanks and piping. Welding is performed using resin welding rods. We can accommodate items ranging from small to large. Quality inspections can be conducted depending on the product size, as follows: ■ Liquid tanks... Water leakage test by filling with water. ■ Air tanks... Air leakage test by submerging in water. For more details, please contact us.

This is an introduction to water jet processing as a response to fine cutting processing of rubber and sponge. Are you having trouble with processed products such as small round holes or narrow long holes? We perform processing with a nozzle that has an injection port of 0.1 mm, so depending on the material and thickness, it is possible to create shapes that cannot be reproduced with press processing or plotter processing. Depending on the material and thickness, plastic cutting is also possible. Thanks to water jet processing, it is possible to create shapes where the cut-out part does not have a blade radius. (Please refer to the photo.) If there are shapes you thought were impossible to achieve, please consult with us.
