Rapid Tooling & Rapid Prototyping

WeLink named as it’s excellent Rapid Tooling services in past 10+ years, and serves 100+ global clients. Our rapid tooling and prototype molding services is trusted by very shot lead time, quality parts, low tooling cost and multiple solutions.

Silicone Tooling – For prototype stage. Low volume 10-50 pieces per mold, can make several molds to get 100-500 pieces, lead time 3-5 days.

Aluminium Tooling – For prototpye, low volume production. Low volume 500-2,000 pieces for ideal. This process offers more scope for modifying tooling later if required. Lead time 3-7 days.

P20 or 1.1730 Steel Tooling – For low-medium volume production.Low-medium volume 1,000-10,000 pieces. semi-automatic or automatic injection molding based on quantity, semi-automatic save tooling cost 50%. Lead time 3-7 days.

Rapid Prototyping China

Rapid Manufacturing China or Rapid Prototyping China is a core and superior service in WeLink. The main technologies include 3D Printing, CNC Machining, Vacuum Casting and Sheet metal. Our 3D printing shop has 50+ SLA industrial printers, max whole print 1,400mm length part, 10+ SLS printers and 5 SLM printers. We have 50+ 3/4/5 axis CNC milling machines, 1/3 of them are imported from Japain and Germany. Vacuum Casting could make a whole part as big as 1,000mm. Sheet metal is precision and good surface finishing. We can not only make precision and quality prototype parts, but also can support client with assembly and test.We can provide many kinds of surface finishing, so no matter function prototypes or appearance prototypes, WeLink is always a good choice.

Low-Volume Manufacturing

Low-Volume CNC Machining & Turning As one of our core services, WeLink is equipped with 50+ CNC milling machines and 30+ CNC turning machines to meet our clients’ low volume CNC machining requests. Our frequently-used metal includes Alumium 7075 -T6, 6061; SS316, SS304, etc. and support with nutural, color or hard anodizing etc surface finishing. Tolerance can meet ISO 2768-f, ISO 2768-m, ISO 2768-mK.

Low-Volume Injection Molding This is a feature service in WeLink. We make prototype tooling or prototype mold using fast-made metal like 7075 or 1.1730 to finish mold in 3-7 days then injection molding 500-1000 units plastic parts in 1-3 days.

Low-volume manufacturing in WeLink has very good timing and pricing advantages. Each project we make 1-3 samples to send to client to confirm the dimensions, tolerences and surface quality. During production, our QC fully check up the first 10 units and make at least 20% sampling ratio. In this way, we promise quality delivery each time.
