We are dedicated to providing prompt and enthusiastic responses to our customers. If you are seeking a manufacturer capable of addressing questions during the prototyping stage or meeting urgent delivery dates, please feel free to contact us.
What products do you manufacture?
We mainly manufacture industrial products and parts, and are also specialized in insert molding using engineering plastics.
What is the maximum quantity you can handle for prototype molds?
We will proactively consult with you, considering your application and budget.
For instance, prototyping with aluminum steel material, we typically consider 1,000 shots as the normal limit, ensuring cost-effectiveness.
On the other hand, for prototyping with general steel (pre-hardened steel), there are no shot limitations, but the costs tend to be higher.
We will assess in detail factors such as speed, budget, and other considerations to provide you with the most suitable proposal.
What resins can be used?
PA6 (nylon 6), PA66 (nylon 66), PA11, PA12, PPS, PEEK, PEI, Ultem, PSU, PSF, LCP, PAI, POM, TPE, PBT, PET, PC, ABS, PP, PS, PE, We can handle all types of materials such as PPE, PMMA, and other thermoplastic resins.
