OUR PRODUCTS
We promise predictable peformance & provide materials, tooling, and manufacturing under one roof

We manufacture rubber and plastic components through compression, transfer, and injection moulding, supported by in-house rubber mixing and compounding. Plastic injection moulding and rubber extrusion capabilities allow precise control over materials, dimensions, and performance across a wide range of industrial applications.

We design and manufacture wear and screening products for mining and industrial operations, including screen media, wear panels, liners, impact bars, and polyurethane components. These systems are engineered to manage impact, abrasion, and continuous operation while extending equipment service life.

We develop custom engineered components using rubber, plastic, and metal combinations. In-house bonding, tooling, and fabrication enable precision assemblies, vibration-control systems, and engineered rubber parts designed to meet specific mechanical and environmental requirements.
