Plastic Rim Production

The following steps are followed to produce a plastic rim for the wheelbarrow wheel:

  1. Mixing and Heating

We use pure raw plastic wheelbarrow rim material to prepare the production. The raw materials are mixed and heated to form a molten plastic material. The color depends on the customer’s barrow wheel order requests.

  1. Injection Molding

The molten raw plastic material is injected into a mold cavity under high pressure. The plastic is cooled and solidified in the mold. Then, the molds are opened and the finished plastic rim is ejected. At Karman, we have comprehensive wheelbarrow wheel plastic rim molds. However, we can always customize according to your drawings if you have specific requirements.

  1. Trimming and Finishing

Once the plastic has cooled, any excess materials are trimmed away from the rim. The rim is then finished by smoothing out any rough edges or surfaces. We arranged inspector to guarantee the plastic rim is in good shape. Bad shape will be picked up to be recycled.

  1. Quality Control

The finished plastic rims are inspected for defects. They are also tested to ensure they meet the required specifications. Then, the inner rim and PU wheelbarrow part are pressed together. Rubber wheelbarrow tire and tube are installed together with the rim.
