Rubber Dust Cover / Rubber Dust Cap – High-Quality Sealing Solutions | RHmould

Product Overview

A rubber dust cover (also called rubber dust cap or rubber dust seal) plays a crucial role in protecting mechanical components from dust, debris, moisture, and environmental contaminants. It is commonly used in electrical, automotive, hydraulics, machinery, and industrial equipment.

At RHmould, we specialize in custom rubber dust covers fabricated with precision molding, robust materials, and tight quality control. Our solutions help prolong the lifespan of bearings, connectors, gearboxes, and other critical components by providing effective sealing and protection.

With over 20 years experience in OEM/ODM manufacturing, RHmould ensures that each rubber dust cover meets the required specifications, tolerance, and performance standards across diverse environments.

RHmould supports multiple rubber compound options and can recommend the suitable material based on your application environment and performance demands.

Manufacturing & Molding Process

We leverage advanced rubber molding techniques and machining methods to ensure precision and repeatability.

Typical Process Flow:

1. Material Formulation & Mixing — Batch mixing rubber compounds with additives, curing agents, and colorants.

2. Tooling & Mold Design — CNC-machined molds with precision cavity design and venting.

3. Compression / Injection Molding — High-pressure molding to shape parts uniformly.

4. Post-curing & Annealing — Stabilize mechanical properties and relieve stress.

5. Trimming & Finishing — Remove flash, trimming edges, checking dimensions.

6. Quality Inspection & Testing — Dimensional checks, hardness measurement, compression set, leak / sealing test.

Throughout the production, RHmould engineers monitor every parameter to maintain consistency and reliability.
