Material Preparation
– Selection of Raw Materials: Most thick rubber blocks use elastomers such as SBR, NBR, EPDM, CR, and natural rubber. The selection depends on desired properties—e.g., chemical resistance, elasticity, abrasion performance.
– Compounding: Raw rubber is blended with additives, fillers, reinforcing agents, curatives, anti-aging substances, plasticizers, and colorants in precise ratios. This mixture is prepared using internal mixers or two-roll mills to ensure uniform dispersion, which directly impacts the mechanical and chemical properties of the end product. -
Forming and Shaping
– Molding Processes: Two common methods—compression molding and extrusion—dominate thick rubber block production. Compression molding, suitable for thicker, denser blocks, applies heat and pressure to vulcanize the rubber in custom molds. For square or custom profiles, die-cutting from pre-cured sheets may also be used.
– Vulcanization: Critical for transforming soft raw rubber into a resilient, durable product. Molds are heated (typically 140–180°C) under prescribed pressure, activating crosslinking agents. Controlled timing ensures dimensional accuracy and optimal hardness. -
Post-Molding Processing
– Trimming and Finishing: After demolding, blocks undergo trimming to remove flash and achieve precise dimensions. Surface finishing (buffing, cleaning) may be performed for enhanced aesthetics or to facilitate downstream applications such as adhesive bonding or surface treatments.
– Assembly (if applicable): For multi-layer or composite blocks, additional assembly steps—like lamination or adhesive bonding—are performed under controlled environments. -
Final Inspection and Packaging
– The completed blocks are sorted by batch, sampled for quality checks, and safely packaged to maintain integrity during storage and transport.
Key Manufacturing Techniques and Innovations

Frequently Asked Questions (FAQs) for B2B Buyers of thick rubber block
-
How should I vet suppliers of thick rubber blocks from overseas markets, such as China?
Diligent supplier vetting is vital to mitigate risks. Begin by verifying company credentials, including business licenses and ISO or SGS certifications. Request product samples to assess quality and consistency. Seek references from global clients, particularly in regions similar to yours (Africa, South America, the Middle East, or Europe). Utilize B2B and third-party inspection services to validate factory operations and ethical standards. Favor suppliers with a proven export track record and responsive communication, as these factors heavily influence reliability, compliance, and long-term partnership potential. -
Can thick rubber blocks be customized for specific industrial applications and local regulations?
Most manufacturers offer robust customization options. You can specify dimensions, hardness (Shore A), material composition (SBR, EPDM, NBR, etc.), colors, and performance criteria (e.g., oil or UV resistance). Provide precise technical drawings, intended use cases, and regional regulatory requirements to ensure compliance—especially important if your market has unique standards. Clarify certification needs upfront (e.g., REACH, RoHS, or regional fire safety norms). Collaborate closely throughout the product development cycle, and always verify samples and technical datasheets before placing bulk orders. -
What are typical minimum order quantities (MOQ), lead times, and international payment terms?
MOQs for thick rubber blocks vary, but most Chinese or global suppliers set thresholds between 100-500 units, depending on customization and material type. Standard lead times span 2-6 weeks for production, plus 1-4 weeks for shipping, depending on location and seasonality. For payment, common terms include 30% deposit upon order and 70% balance before shipment.
