Koves Plastic Industries is a custom injection molder specializing in engineering materials and components. Our biggest asset is our people: our staff features: engineers, CAD experts, toolmakers and injection molding troubleshooters with more than 100 years of combined experience in the industry. We have attempted to import some of that knowledge into our Design Guide, which is designed to be an informative, easy to follow reference guide that we hope you go back to again and again.

CASE STUDY: The Hand Chain Sprocket wheel.

Koves Plastic Industries replaced metal components with strong lightweight plastic alternatives and created a customised lightweight solution for a client with a weight problem.

Koves created a 2-piece plastic Hand Chain Sprocket wheel, designed to maximise strength and minimise material use. It offers a 90% weight reduction when compared to the previous metal sprocket wheel. Click on the picture to read the Case Study.

Light Weight but Strong Plastics



Koves Plastic Industries successfully developed a conduit separator for the Transpower Naan project.  Koves developed a plastic ‘I’ Beam and Cradle, that set the position and height of three 250 mm dia conduits in a two metre deep road trench.  Plastic was sourced that met thermal resistivity requirement for the 220 kV conduits. The strong and lightweight design, allows easy transportation, handling and sped up the trenching process. The improved productivity reduced the costs for the contractor and minimised the impact that the open trench had on traffic and communities.  Click on the picture to read the Case Study.
