Basic Manufacturing and Process Control
Our metal components are made using progressive stamping tools on pneumatic presses with controls for dimensional accuracy. Post stamping, a nine step process is followed for surface pre-treatment, de-greasing, rinsing, de-rusting, phosphating and powder coating. This ensures adequate salt spray (anti-corrosion) life for metal frame structure.
Our basic rubber compound formulation uses 100% natural rubber in highest grade and is optimized for tear resistance, low temperature flexibility and noise reduction. To give our customers a durable, consistent, smooth, streak, and chatter free wipe, we check physical properties in all our rubber batches to ensure controlled mixing and pre-forming. Temperature, curing time and de-flashing controls are integrated into molding and surface coating processes. Chlorination and Slitting, the two most critical operations post molding, are done with programmed logic for consistency and precision.
We test for quality and properties of the basic raw materials and chemicals used, as well as for abnormalities in rubber curing and profile. We perform tensile, abrasion, heat aging and chemical tests of rubber compound and an initial wipe quality test of finished product as a part of our routine quality assurance protocol.
Frame assembly uses embedded brass rivets and plastic springs to avoid direct metal-to-metal contact in the structure and ensures corrosion resistance and noise reduction. Stainless steel flexor wire straightening, rubber assembly and pressure distribution checks are performed as a part of the process.
