Our Experience in Plastic Gears

Our Gear Capabilities

With the capability of handling gear precision of up to AGMA 8 or DIN 8, Kore Industries is producing gears for gearboxes in industries such as electric cars, e-drives, consumer electronics, medical devices, robots and industrial products.

Most frequently, our Gear Engineering Team work closely with customers at the pre-production stage to discuss design, identify problems and brainstorm with them to ensure risk at mold production stages are kept to a minimum.

Our Design Engineering Team also work closely with our customers to do the appropriate DFM and mold-flow analysis prior to build, to ensure the highest standards and delivery.

Our Gear Quality Control

Our gears pass through stringent gear inspections and procedures. From checking the profile of our gear electrodes, we also ensure that the gear molds are built to specification.

Our products are checked with our OSAKA Double-Flank Gear Roll Tester to validate teeth-to-teeth tolerances as well as radial concentricity.

We also look into common issues that our customers face, such as:

  • Excessive noise level
  • Premature gear teeth wear
  • Gear teeth breakage
  • Excessive power draw on motor
  • Premature wear and tear on power unit
  • Overheating of gearbox

What Are Plastic Gears?

Plastic gears are a specialized component that are typically found and used in machinery. These small or large components often vary in size, and are typically found in the shape of a cone or a cylinder. These pieces are designed with equally-spaced teeth that are cut into the surface, so that when two plastic gears are meshed together, they facilitate force, rotations, and resistance from the shaft that drives them, to the shaft that is being driven.

Gears allow for the movement of multiple shafts in a single, continuous motion by transferring movement from one to another. At Kore Industries, plastic gears are a major aspect of what we do. And because we specialize in the production of plastic parts, we frequently manufacture plastic gears that are applied in a number of different industries and use cases all throughout the world.

Gears can be classified into the following shapes:

  • Involute Gears
  • Cycloidal Gears
  • Trochoidal Gears

Shaft positions can be classified into the following positions:

  • Non-Intersecting Shaft Gears
  • Parallel Shaft gears
  • Non-Parallel Shaft Gears
  • Intersecting Shaft Gears

What Are Plastic Gear Molds?

In order to manufacture plastic gears, we use a molding process – similar to that of our other molding processes. Our process begins with a plastic injection mold that features gear cavities. From there, we use molten plastic to create the gear. Once the molten plastic is poured into our mold and cools, we are left with a solid gear component that is ready for production use and application.

The Benefits of Plastic Gears & The Plastic Gear Mold Process

Because the plastic gear mold process is quite simple, Kore Industries is able to produce them at a rapid pace, which helps to ensure that machines and equipment all throughout global industry have the components that they need to continue functioning.

In addition, we use impact resistant plastics to craft our gears, which helps to bring a reliable, durable, and long-lasting component to the market, which helps to save on maintenance and upgrade costs for our clients. We understand just how important these plastic parts and components are for our clients, and we strive to ensure strength and hardness throughout the entire lifeline of these products.

The Different Types of Plastic Gears

Plastic gears come in many different types and forms – all depending upon their uses, their purposes, and their applications. Different gears may function differently from others, and things like dimensions, face width, number of teeth, and helix angle combine with other important factors like precision standards and torque requirements to ensure that the gear you’re looking to have produced is most effective for the product you’ll be using it for.

Some of the most common types of gears that we produce include:

  • Spur Gears
  • Helical Gears
  • Worm Gears
  • Bevel Gears
  • Rack and Pinion Gears
  • Internal Gears
  • Miter Gears
  • Screw Gears
  • Fan Gears

Areas Where Plastic Gears Are Best Applied

When it comes to plastic gears, their uses and applications are quite wide-ranging. Because they can be mass produced in different shapes, in different forms, in different sizes, and for different load capacities and thrust directions, plastic gears are used throughout a number of industries all around the globe.

We product plastic gears for the automotive industry, electronics, and even medical products. We encourage you to reach out to us directly, should you have any questions regarding our plastic gears and plastic gear production.
