Well, there are lots of caster wheels available in the market, but do you know how they are manufactured?

Keep on reading the complete manufacturing process guide from Sturdy Lenva casters to know “how do we do it”.

This guide will provide descriptions of each step of the production of caster wheels starting from raw material.

Casters are generally divided into two major parts: plastic and hardware, which have different production processes.

Hardware parts include a top plate, yokes, ball-bearing raceways, etc. Wheel parts have the plank wheel, bearings, bearing covers, etc.

Below are further details of these two parts.

1 Manufacturing process for hardware parts

Step 1: Metal Molding Manufacturing
This is where we begin to make the casters from the concept. After confirming all specifications of caster wheels, then start tool making. We make all of the metal moldings and stamping moldings our own. This enables us to produce custom casters for you. Meanwhile, regular tool maintenance and repairs could ensure the production capacity.

Step 2: Roll Sheet Cutting
After receiving the coil steel sheet, our technician will cut the roll sheet to different sizes as there are different kinds of caster sizes and top plate dimensions.

Step 3: Stamping / Forming
Our comprehensive stamping machines, like CNC punching machines, automatic machines, hydraulic press machines, ensure that thicker steel sheets can be stamped and formed without any failure. Stamping workshop processes the production line of bending, stretching, forming, drilling holes.

Step 4: Welding
The extra process of welding the caster yoke is needed for heavy-duty or super heavy-duty casters. Double welded legs could increase the strength and loading capacity than typical caster types. Our experienced welding staff consistently ensure the welded joint quality by manual and automatic welding processes.

Step 5: Surface Plating
There are various surface plating options for your selection, such as zinc plating, chrome finish plating, brass plating, and more. Surface plating to caster hardware parts could not only provide an attractive appearance but also increase chemical resistance for anti-rust and anti-corrosion.

2 Manufacturing processes for wheel parts

Step 1 Plastic injection molding
Plastic injection molding plays an important role prior to mass production. As the wheel part is different from the hardware part, most of the wheels are made by one-step injection molding. The appearance of wheel size, performance, and other parameters are molded after injection and forming. This could not be changed. So, it’s essential to ensure the accuracy of plastic injection molding.

Sturdy has a variety of injection molding machines that could produce many wheels, like nylon wheels, polyolefin wheels, polyurethane wheels, TPE wheels, TPR wheels, high temp wheels, and a lot more. And the cycle time for each molding set is customized for different caster wheel materials.

Step 2 Drying plastic resins
Drying plastic resins is the process for dehumidifying resins to avoid the problems that may be caused by too much moisture in the plastic pellet.

Step 3 Injection and Forming
Fill the dried plastic resins into the injection machine. After the specific cycle time, the wheel will be formed and completed. Cut the edge gate of the wheel tread and then cool down the wheels. Plastic wheels are usually cooled naturally by water.

Step 4 Assemble the bearings to the wheel
The last step for wheel parts is assembling the bearings to the wheel. It could be finished by automatic machine or by manual. It depends on the wheel size; smaller wheels such as the 1-inch wheel, 1.5-inch wheel, 2-inch wheel, etc., could be assembled by automatic machine.

3 Manufacturing process for hardware + wheel parts

After completing the above two individual processes for each part, then the assembly workshop for these two components comes together. For yoke and wheel assembly, it’s a combination of manual labor and semi-automatic production lines. This leads to the economical, efficient assembly work for producing the highest quality caster wheels.

For semi-automatic production lines, could accept the large quantity orders. Small orders could be completed manually.

Finally, pack the finished caster and wheel products. According to the requirements, there are consumer packing for casters (could be sold directly in the supermarket or hardware store), suitable packing way for Amazon sellers, pallet packing for sea shipment.

Whether you need standard or custom caster and wheels, Sturdy has the machinery and workforce to bring your casters to life. Sturdy caster specialists can help you to select the most suitable Lenva caster types for your applications.
