Polycraft - Welcome to Roots Cast Private Ltd

About Us

Roots Polycraft (RPC) is a leading manufacturer of plastic injection moulding components. We cater to a wide range of automotive and industrial applications with precision and reliability.

Our expertise lies in processing various thermoplastic polymers using state-of-the-art injection moulding machines, including vertical (45T) and horizontal (50T to 550T) setups. As a trusted name in the industry, we deliver plastic injection moulding components designed to meet the highest standards of durability and precision.

Beyond injection moulding, we provide advanced solutions such as plastic ultrasonic welding, stored energy welding for metal inserts, plastic extrusion, and sub-assembly services, ensuring a comprehensive range of offerings for our clients.

Our experienced team is adept at handling complex moulds and challenging raw materials, ensuring precision and quality in every component we produce.

Horizontal Injection Moulding

Horizontal Injection Moulding is a widely used plastic moulding process where molten plastic is injected into a mould cavity under high pressure. This method ensures consistent production of intricate and high-precision plastic components with excellent surface finish. The horizontal orientation of the machine allows for efficient production cycles.

Roots Polycraft specializes in manufacturing high-quality plastic components using advanced Horizontal Injection Moulding technology. Our facility is equipped with state-of-the-art machines ranging from 50T to 550T clamping force, enabling the production of a wide range of components with superior dimensional accuracy. With capabilities such as tight tolerance control, and high-volume production, we cater to industries like automotive, electrical, and industrial applications.

Vertical Injection Moulding

Vertical Injection Moulding is ideal for insert moulding applications, where metal inserts are encapsulated in plastic during the moulding process. In this method, the mould closes in a vertical plane, ensuring better control and precision for over-moulding operations.

Roots Polycraft's Vertical Injection Moulding solutions cater to industries requiring high-accuracy plastic moulded components with embedded inserts. High-precision components are guaranteed through vertical injection techniques, starting from low-volume runs to high-volume productions. Critical quality control processes at Roots Polycraft ensure every product performs to the required specifications, maintaining the highest standards in every production cycle.

Ultrasonic Welding

Ultrasonic Welding is a high-frequency welding process used to join thermoplastic components without the need for adhesives or fasteners. This technique utilises ultrasonic vibrations to create localised heat, ensuring a strong, precise, and reliable bond between plastic parts.

Roots Polycraft’s Ultrasonic Welding facility is equipped with advanced ultrasonic welding machines designed for high-speed and precise bonding. Ultrasonic welding allows for high-volume production with no curing times or additional materials required. Strict quality control ensures that every welded component meets your requirements for strength, appearance, and performance.

Plastic Extrusion

Plastic Extrusion is a continuous manufacturing process used to produce long plastic profiles with uniform cross-sections. Molten plastic is forced through a die, forming tubes, sheets, and other complex profiles suited for industrial applications.

Roots Polycraft specialises in high-quality Plastic Extrusion solutions, delivering durable and precisely engineered extruded components. Our facility is equipped with advanced extrusion machines capable of handling various thermoplastics and custom profiles, ensuring reliable performance in applications such as tubing, seals, and specialised plastic profiles.
