Prototyping Services

As an OEM factory, we developed a large number of projects successfully in the past years! 90% of them are new in the world and Some of them need a prototype to test the function before making molds and mass production.

So the Prototype service is necessary! MAXWISE has very reliable contracting factories whom could help make prototype.

Stereolithography (SLA) & Selective laser sintering (SLS)

SLA

Used to build concept models, cosmetic prototypes, and complex parts with intricate geometries.

Material options: SOMOS 14120, SOMOS 11122, Lasty(UTR6180), etc.

Tolerance: +/-0.1mm (0.002in) (may change per part geometry)

Properties: Parts come out with good quality surface finishes for cosmetic prototypes with high accuracy and features.

Lead Time: 1 to 3 days

SLS

Used to create highly durable final parts that require heat resistance, chemical resistance, flexibility, or dimensional stability, suitable for producing accurate prototypes, mechanical models and functional production parts

Material options: Nylon, PA2200, PA3200GF, ABS, TPU etc.

Tolerance: +/-0.1mm (0.002in) (may change per part geometry)

Properties: More economical option when higher volumes of 3D-printed parts are required. SLS parts are more substantial than the SLA counterpart, but their surface finish is not good as the SLA ones.

Lead Time: 1 to 3 days

Vacuum Casting Service

Vacuum casting, also called Urethane casting or Polyurethane casting which uses silicon moulds to make a high-quality prototypes of plastic and rubber components by using polyurethanes resins. It’s a low-cost, productive and efficient solution for making high quality small batches of prototypes.

Advantage & Disadvantage of Vacuum Casting

Advantage

  • Master pattern components can be used within 24hrs, reducing prototyping time and cost for new products.

  • Multi-segment moulds & cores can accommodate complex shapes and features, and aluminium and brass in-mould inserts are also viable.

  • Vacuum casting creates high-quality injection moulding type parts for prototypes or low volume end-use parts in benign environments. A wide range of resins is available for various applications, including clear, rubbery, flame retardant, food-grade, and colored. Resin type can be changed without retooling to test various materials for an application.

Disadvantage

  • The mould made of soft silicon wears out quickly, lasting only for about 30-50 parts. The wear depends on the size, surface textures, and features. Mould life is reduced by bigger parts, rough textures, and many proud features.

  • Shrinkage occurs due to thermal expansion, with a typical rate of 15%-0.25%. Deviations from normal tolerance may occur due to irregular, overly thin or thick features. The manufacturer generally allows for shrinkage tolerance, but it’s worth confirming before placing an order.

  • Post-processing determines the surface finish, which may be limited to the outside only. Sharp corners and texts may have rounded edges, and some features require plugs and cores.
