ISO9001 Vacuum Casting Rapid Prototyping Plastic ABS Rapid Prototype Molding

Vacuum Casting Small Batch Production And ABS Plastic Rapid Prototyping Parts

Vacuum Casting ​:

  Vacuum casting is a swift, budget-friendly method for replicating top-notch plastic parts, akin to injection-molded items. It employs dual-component polyurethanes and silicone molds crafted from a 3D-printed prototype. This approach is ideal for testing fit and function, marketing needs, or producing limited runs of final-use components.

1. Rapid prototyping
       and full-scale production

2. Used in over
       20 countries

Vacuum Casting Process

   Creating polyurethane vacuum cast parts involves three main steps: master pattern creation,

mold fabrication, and part casting.

1. Master Pattern Creation:

   Crafting patterns from your CAD designs is the initial step. These 3D solids are made through CNC machining or 3D plastic printing like SLA/SLS. You can provide patterns or let us create them. Patterns should endure up to 50°C heat.

2. Mold Fabrication:

   Liquid silicone forms the casting molds. It's poured around the master pattern within a casting box, cured in an oven for 15 hours. Afterward, the mold is opened, and the master pattern is removed, yielding a negative cavity mirroring the original. Our silicone molds typically yield around 25 copies of the master pattern.

How does vacuum casting work?

The process involves 3 main stages:

• Building a master model
• Creating the silicone tool and
• Producing the parts

Building a master model:   To achieve precise results in vacuum casting, start with a top-notch master model. Crafted via 3D printing or CNC machining, it's meticulously refined for ideal surface texture and detail replication.
Creating the silicone mould tool:   Create precise silicone molds by encasing the master model in a casting box filled with liquid silicone. Maintain a 40°C temperature for 8-16 hours until the silicone sets. Once cured, cut open the mold to reveal a perfect fit for your master model.
Producing the parts:   Fill the hollow mold with polyurethane (PU) resin through a funnel to ensure even distribution and prevent air bubbles. Seal the mold and let it cure at 70°C in a casting machine. After cooling, remove the shaped material, and perform any required post-processing. Typically, this process can be repeated 10-20 times before the mold's shape starts to deteriorate, affecting accuracy.

Benefits Of Vacuum Casting

Vacuum casting offers efficient manufacturing of intricate shapes with high precision, cost-effectiveness, and versatility:

• Easily create complex shapes with precision.
• Simultaneously produce multiple components for enhanced efficiency.
• Rapidly prototype using quality urethane for small batches.
• Diverse material properties with different polyurethanes.
• Economical manufacturing due to low polyurethane costs.
• Efficient silicone mold production compared to metal molds.

In the end

Vacuum casting offers cost-effective, efficient production compared to traditional methods like injection molding and die casting. It excels in small batch production and rapid prototyping due to its low cost.

However, it's less efficient for mass production as it's limited to casting a small number of products at once. Vacuum casting is perfect for custom, low-volume manufacturing due to its adaptability and versatility.
