Can you handle it individually?Yes. We also have a track record of ordering from individual customers. We can handle making molds and large quantities production or making only one product. The price will change depending on the quantity. Also, the molds is expensive.
Can you handle it even if I don’t have a drawing?We will ask you about the environment in which the product is used (temperature, indoors /outdoors, strength, etc.), and we can propose material selection based on the shape, so please contact us.
What is the minimum lot qty?It is possible from one. We can supports small quantity, high variety, and variable variety. Please contact us as the price will vary greatly depending on the processing method.
How long is the delivery time?We emphasize customer satisfaction rather than deliverytime in order to provide better products. Therefore, if the shape of the mold is fixed, we will provide the 1st try in 30 to 45 days and a good product in 2.5 to 3 months.
As a result, from the product concept, there are some long ones that took two years. This is the result of focusing on making products that match the needs of our customers and sticking to uncompromising manufacturing.
Can you give me a development proposal?We are good at product design and development proposals. We make proposals from the standpoint of end users, and also propose efficient manufacturing at the development stage.
Is it possible to jointly development?Yes. It is possible. We join a LLC from various industries and
have a ssocations with mechanical designers , so we will respond to your neede in one stop.
Let’s share the suffering and joy while making things toward the fulfillment of the development project.
Can you just make a prototype?
Of course it’s okay. Since process inspections are carried out in each process, we also accept requests for trial production, molds, molded products, and assembly.
What materials do you handle?We handle thermoplastic resins. Typical products include PE, PP, POM, ABS, PS, PC, PBT, PMMA, PA, various elastomers, and various filler-reinforced resins (glass, carbon, etc.) added to the above-mentioned resins up to 30%. In particular, we are actively working on transparent resins that other companies tend to avoid.
Is the transparent product molding machine a dedicated machine?No, it is not a dedicated machine.But we have know-how in cleaning the inside of the heating cylinder, and we have equipment that makes it difficult for carbides to be generated, so we can handle it even if it is not a dedicated.
Black spots on products, so-called foreign substances, are carbides generated during molding in the heating cylinder that melts the material.
What is flow analysis?Before making a mold, “visualize” how the material flows, detect predictable defects, incorporate countermeasures into the mold making, and shorten the trial period after the mold is completed. And optimize molding It is a plan.
Can you make resin products what is substitutable to metal parts?We will ask you about the purpose and result of what kind of application it will be used for and what will happen when you actually use it, and we will propose it according to your needs.
How thick is the product possible?We have a track record of 20 mm for PCs and 25 mm for POMs It’s depending on the material, shape, and gate.
Is it possible to paint or print on resin parts?Yes, we can handle from one. We will provide you with the most suitable processing method that meets your needs.

Is it possible to process or manufacture products other than plastic and rubber?
Total coordination from product design to shipping is possible. We manufacture and procure materials necessary for products such as design, metal parts, plastic parts, board circuits, screws and connectors, and provide them under strict quality control.
Can you handle medical device products / parts?We have many achievements in molding with materials that are resistant to chemicals. We have various facilities that not to impair the material properties, so please feel free to contact us.
Do you comply with the RoHS Directive?It corresponds. The six specified hazardous substances (lead, cadmium, mercury, hexavalent chromium, PBB, PBDE) of the RoHS Directive are covered. (This does not apply to exempted items.) Please let us know at the time of negotiation.
Can you give me the analysis data?In order to confirm compliance with the RoHS Directive, we are conducting confirmation work by acquiring analysis data from each business partner and analyzing and measuring with fluorescent X-rays. Please contact us whenever you need analysis data.
