Exercise Equipment elastic Hip Circle Resistance Bands extruding machine factory

Extrusion is a common manufacturing process used to make resistance bands and other rubber products. It involves forcing raw rubber material through a die to form the desired shape.

The raw rubber material is first mixed with fillers, pigments, antioxidants, and other additives to achieve the desired properties. This material is fed into an extruder machine.

The extruder heats and presses the rubber material through a shaped die, forming a continuous length of material with the desired cross-sectional profile (e.g. round, flat).

As the extruded material emerges from the die, it passes through a water bath to cool and set the shape.

The cooled extrusion is then cut to length by automated cutters to produce individual resistance bands.

Additional finishing steps may include trimming, smoothing, printing logos, adding attachments, and packaging.

Factories contain multiple extrusion lines working in parallel for high volume production. Quality control checks are performed throughout the process.
