The RubberQ Standard

Our two-stage mixing process — run on a single, dedicated A-mixing line designed with our Japanese formulation partners — is the backbone of our quality promise. By separating masterbatching from final compounding, we achieve superior batch-to-batch consistency across years of production for critical EV, semiconductor, and Tier 2 automotive applications.

Phase 1: Material Sourcing & QC

Raw Material Receiving

Incoming inspection of polymers and chemicals according to IATF 16949 8.4.2 standards.

Controlled Warehousing

Environmental monitoring and FEFO (First-Expired-First-Out) storage management.

Phase 2: Masterbatching (Stage 1 Mixing)

A-Formulation

Precise weighing of masterbatch components using automated dosing systems.

Internal Mixer (A-Mixing)

High-shear mixing in Banbury equipment to ensure uniform dispersion of fillers.

Calendering & Cooling

Sheet extrusion followed by rapid cooling to stabilize the compound.

Masterbatch Testing

Verification of Mooney viscosity and specific gravity before moving to stage 2.

Single Line, Zero Cross-Contamination

Sequence-ordered scheduling: highest-purity compounds first in the day, high-carbon-black and peroxide-cured compounds last. SOP-driven cleaning between batch families. Critical for semiconductor FFKM and EV battery seal applications where compound purity cannot be compromised.

Phase 3: Final Mixing (Stage 2 Mixing)

B-Mixing (Final Compound)

Addition of vulcanizing agents and accelerators under strict temperature control.

Maturation/Aging

Controlled storage to allow material relaxation and chemical stabilization.

Final Compound Testing

MDR (Moving Die Rheometer) testing to verify curing curves and performance.

Phase 4: Molding & Finishing

Precision Molding

Utilizing vacuum compression and injection molding for high-tolerance components.

Deflashing & Trimming

Removal of excess material using cryo-deflashing or high-precision manual trimming.

Phase 5: Quality Guarantee & Logistics

Final 100% Inspection

Dimensions, appearance, and physical properties verified against customer specs.

Global Fulfillment

Barcode-tracked packaging and international shipping via port-proximate logistics.

Advanced Process Control

Every batch produced at RubberQ is managed via our integrated ERP system, ensuring 100% traceability from raw material lot number to the final part shipped. We utilize SPC (Statistical Process Control) to monitor critical parameters in real-time.
