Products Description

Vacuum Casting Soft Rubber Products refer to flexible components manufactured using the vacuum casting process with soft rubber, rubber-like, or elastic polyurethane materials as raw materials. These products are typically formed using silicone molds, where liquid material is poured under vacuum conditions to replicate the structure, texture, and dimensional details of the original prototype.

Compared to traditional injection-molded soft rubber parts, vacuum-cast soft rubber products are better suited for projects requiring small batches, multiple variants, and rapid design validation. Their materials can simulate various rubber properties, such as soft tactile feel, high elasticity, abrasion resistance, tear resistance, and moderate oil resistance and aging resistance. They meet diverse needs including functional testing, appearance evaluation, and market validation.

In practical applications, Vacuum Casting Soft Rubber Products are not only used for final functional parts but also commonly employed in Engineering Verification Tools (EVTs), Design Verification Tools (DVTs), and small-batch trial production phases. This enables customers to thoroughly validate product design feasibility and market acceptance before proceeding with formal tooling.

Advantages and Features

1. Low Cost, High Cost-Effectiveness

Vacuum casting eliminates the need for expensive steel molds, requiring only silicone molds for production. This significantly reduces upfront investment costs, making it particularly suitable for startup projects or new product development phases.

2. Fast turnaround and flexible response

Typically requiring only 7–15 days from 3D data to finished product, we can swiftly address urgent customer needs and accelerate time-to-market.

3. Diverse Material Options

Multiple soft rubber and rubber-like materials are available, offering a wide range of hardness levels (Shore A 10–90) to simulate the distinct tactile sensations and properties of TPR, silicone, rubber, and other materials.

4. High Fidelity to Original Appearance

Silicone molds excel at replication, accurately reproducing the texture, chamfers, logos, and intricate details of the original part with superior surface quality.

5. Suitable for small-batch production

A single mold typically produces 15–30 pieces, making it ideal for multiple iterations and version testing while avoiding inventory pressure.

Production Process Flow

Prototyping

n of power distribution systems for the petrochemical industry.

Silicone Mold Fabrication

Secure the master mold within the mold frame, pour liquid silicone rubber, and cure it to form a reusable silicone mold.

Vacuum Infusion

Under vacuum conditions, pre-mixed soft gel material is injected into the mold, effectively preventing air bubbles and enhancing the quality of the finished product.

Curing and Molding

The material cures at room temperature or under heated conditions to form the final soft rubber components.

Post-Processing

This includes deburring, surface finishing, spraying, coloring, screen printing, or simple assembly to meet customers' further requirements for appearance and functionality.
