General Manufacturing QA
01:How many qualified casting parts can be made from a single silicone mold?
2022-07-26
Generally, except scrapped castings, one silicone mold is available for approximately 20pcs good parts, but it depends on the specific geometry of the object and dimensional and surface finish requests.【detailed】
02:How big casting parts can we produce by silicone mold?
2022-07-26
We can produce whole parts with a maximum size of 1800x800x800 mm.【detailed】
03:What tolerances can Zhiyou vacuum casting hold?
2022-07-26
We provide a standard tolerance on ± 0.15mm/100mm, and the highest precision is able to reach ± 0.05/100mm, but mold life might be 12~15pcs meanwhile.【detailed】
04:Can we produce plastic parts with metal inserts or rubber(2K part)?
2022-07-26
Of course yes. The insert or hard plastic part can be placed in its final position in the cavity and co-moulded. During casting process, the hard plastics/rubber PU material will adhere to the metal/hard plastics, and create the final assembled object accordingly.【detailed】
2022-07-26
Yes. Our casting resins are polymers with certain properties similar to engineering production plastics, like ABS, PMMA, PC, PP, PA, POM, etc. Some special materials are also available, like high-temperature resistant (120℃ or 200℃) or fire-resistant (UL94-V0). See our vacuum casting material list in details.【detailed】
06:What materials do we use for rapid tool?
2022-07-26
Aluminum 7075, P20, NAK80, harden S136, harden H13, etc.【detailed】
07:What production materials can be used for injection molding?
2022-07-26
We can use all thermoplastic materials.【detailed】
08:What materials do we have for CNC machined parts?
2022-07-26
Plastic: ABS, PMMA, PC, PP, PS, POM, PA, PA+GF30, Teflon, DHPE, HDPE, PPS, PEEK, etc.
Metal: Aluminum, Brass, Bronze, Copper, Steel, Stainless Steel.【detailed】
09:What 3D printed materials can be used? and max. part size?
2022-07-26
