Bridge the Gap From Prototype to Production is fully capable of handling your urethane casting and silicone molding needs. With years of expertise in the field, we can fabricate your plastic parts to the highest standard, as well as cost-efficient and with fast turnarounds.

Vacuum casting refers to the use of the original sample plate to make a silica gel mold under vacuum, and the use of PU, silicone rubber, polyester, abs and other raw materials for pouring under vacuum, so as to reproduce the same photocopies as the original sample plate.Contact us today for more information about our vacuum casting services.

The Advantages Of Vacuum Casting

  • No need to invest high initial cost in mold manufacturing
  • The vacuum casting has a high degree of reduction, requiring little or no post-processing
  • Different vacuum casting polymer materials are available, and the required color can be prepared according to requirements
  • The mold can be completed within a few days after the production of the front prototype
  • The die strength can meet 50 times of production
  • Glue coating enables plastics of different materials and hardness to be integrally formed

Custom Manufacturer Of Vacuum Urethane Castings And Silicone Castings

With urethane often being used to mimic or replace injection molded components,Vacuum casting is very suitable for rapid engineering testing, design concept verification, sales and display.ISO 9001 and AS 9100 certified Manufacturer of prototype and short-run production vacuum castings.Be-cu. com’s manufacturing team is good at mold production, and can produce silica gel mold with strength of up to 60 products in a short time. The surface treatment of the products manufactured by duplicate mold is fine.The vacuum casting technology of uses 3D printed templates to make silica gel molds in vacuum, and uses ABS, acrylic, PC, PA, silica gel, soft glue and other materials for pouring in vacuum, so as to clone the same copies as the original templates. A silicone mold can be used at least 20 times.

It can also be used to reproduce or duplicate multiple high quality and relevant prototypes from a master model.Parts can be opaque, translucent or transparent depending upon application. Utilizes silicon molds for castings. Other services such as cnc machining, injection molding, extrusion, sheet metal prototyping, pressure die casting and surface finishing offered. Suitable for appearance models, engineering testing, market testing, proofing and display demos for investor pitches and trade shows. Serves the automotive, aerospace, electronics, energy and robotics industries.

Additive Services Of Vacuum Casting

  • Tolerance: The tolerance of Vacuum Casting products mainly depends on the accuracy of prototype parts, the geometric structure of products and the selected manufacturing materials. Generally, 0.15% shrinkage is acceptable.
  • Materials: Vacuum Casting can have hundreds of materials to choose from, which can achieve different design hardness and surface texture. The products of Vacuum Casting can be completely opaque or translucent, or completely transparent, which can meet various design requirements.
  • Post-Processing: provides a series of post-processing services to ensure that the products fully meet your expectations. Our post-treatment includes sand blasting, painting, polishing, water blasting, drilling, tapping and threaded holes, pad printing, silk screen, etc. We have a professional quality inspection team to check the products, and each project is visible in the production system and tracked by a specially assigned person.

What Is Vacuum Casting

The vacuum casting is to use the original template to make a silica gel mold under vacuum, and use PU or other materials to cast under vacuum, so as to clone the same replica as the original, which is more resistant to high temperature and has better strength and hardness than the original template.The vacuum casting will not damage the original, and the copied product has excellent surface treatment effect.The technology of vacuum urethane casting can be used for two purposes:

  • Small batch manufacturing of rapid prototyping;
  • Change the material; The prototype parts carved with gypsum putty can be changed to PU or POLY materials that are easy to be processed later through copying, or ABS materials can be changed to materials with special requirements (such as those requiring transparency, high temperature resistance, high strength, or rubber characteristics).

3D-Printing Prototype
Before making a silicone mold, you need to make a prototype. At present, the commonly used method is to use 3D-printing to make prototypes.
Silicone Mold Making
After the prototype is ready, start to make the silicone mold. After drying for eight hours, cut the silicone die and take out the prototype. At this time, the silicone mold is ready.
