Products Description
This series of moulded rubber parts adopts high-quality rubber materials including NBR, EPDM, FKM, Silicone, HNBR and CR. All products are integrally vulcanized and molded through high-precision steel molds without splicing or cutting seams, featuring compact internal structure, uniform density, high dimensional accuracy and stable performance consistency. The product line covers various non-standard special-shaped parts such as irregular gaskets, shock-absorbing blocks, limit rubber columns, buffer pads, dust-proof sleeves, positioning plugs and composite rubber bases. It also supports integrated embedding, rubber coating and soft-hard composite molding. The hardness, elasticity, wear resistance, temperature resistance and flame retardancy can be independently adjusted according to actual working conditions to adapt to complex environments of high pressure, frequent vibration, friction abrasion, chemical corrosion and alternating temperature changes. With precise vulcanization technology, the products eliminate burrs, deformation and uneven thickness of traditional cut rubber parts, featuring smooth surface, stable resilience and low compression set. All finished products pass strict dimensional calibration, physical performance testing and aging resistance inspection to ensure long-term and stable operation in various non-standard equipment supporting scenarios.

Product Advantages
Full-coverage non-standard special-shaped customization
Different from standardized O-rings and flat gaskets with fixed specifications, moulded rubber parts support integral forming of any special-shaped structure without size limitation. They can perfectly fit special grooves, irregular installation spaces and personalized assembly structures of various equipment, completely solving the problem that standard rubber accessories cannot adapt to non-standard mechanical structures.
Integrated molding with superior structural strength
Adopting one-piece high-temperature vulcanization molding, the product has no cutting or splicing gaps. The overall structure is compact, firm and evenly stressed, effectively avoiding tearing, deformation and loosening during operation. Its structural stability and service life are far better than ordinary rubber parts processed by post-cutting and manual splicing.


Multi-functional integrated design to simplify assembly
A single moulded rubber component can integrate multiple functions including shock absorption, buffering, sealing, anti-slip, heat insulation, electrical insulation and position limiting. It avoids the superposition of multiple accessories, simplifies equipment assembly structure, reduces the total number of parts and effectively lowers production assembly and daily maintenance costs.
Adjustable physical properties for targeted working conditions
The rubber formula can be customized according to actual application environments, with adjustable hardness, wear resistance, temperature resistance range, flame retardant grade and anti-corrosion performance. It can adapt to various harsh working conditions such as low-temperature embrittlement, high-temperature aging, high-frequency vibration, medium corrosion and static protection.
High precision and excellent batch consistency
Shaped by high-precision integral molds, the products feature accurate dimensions, no burrs and uniform thickness. Mass-produced products maintain extremely high consistency, fully matching equipment assembly tolerances. It effectively avoids assembly jamming, poor sealing and limiting failure caused by dimensional errors, completely meeting the requirements of large-scale standardized supporting production.
Product Q&A
Q: What are the core differences between moulded rubber parts and ordinary extruded or cut rubber parts?
A: Ordinary extruded and cut rubber parts can only produce simple strip and sheet structures with low precision and loose structure, only suitable for basic sealing and padding scenarios. Moulded rubber parts are integrally vulcanized under high temperature and pressure, supporting complex three-dimensional, special-shaped and composite embedded structures. They feature higher precision, denser structure and more stable performance, exclusively customized for non-standard equipment structures and multi-functional working conditions, which cannot be replaced by standard rubber products.
Q: Are custom services based on drawings and samples available?
A: Yes. We support reverse mold opening and mass production according to 2D drawings, 3D models and physical samples. There is no restriction on shape, structure or thickness. Whether it is simple special-shaped gaskets or complex integrated rubber-coated and embedded composite parts, we can achieve accurate reproduction and mass production, covering R&D sampling, equipment renovation and complete machine supporting demands.
Q: Can moulded rubber parts integrate insulation, flame retardancy and corrosion resistance?
A: Yes. Through formula modification and integral moulding technology, a single rubber part can simultaneously achieve insulation, flame retardancy, acid and alkali corrosion resistance, high temperature resistance and shock absorption without secondary processing. It fully meets high-standard protection requirements of new energy, electronic control and precision equipment.
