Production of certified PVC pellets

The proof of having made a good product is in the repeat purchases.

At Granzplast, we are aware of how important quality is for our clients as a strategic factor to compete in the market. For this reason, at Granzplast we have a laboratory for research and development of new products in which we work in collaboration with our customers, suppliers and various technological institutes.

Beyond research and development of tailor-made solutions for clients, at Granzplast we carry out strict quality control of the manufactured pellets. This quality control is supported by two fundamental pillars: the control of the variables of the industrial process and the control of production.

The process control is carried out systematically through internal protocols in all production phases: dosing, mixing, cooling and pelletising.

Production at Granzplast is highly automated.

We have our own development programme for feeding/dosing raw materials for all the components that are manufactured in each of the 4 active production lines. Acceptance limits are controlled throughout the process by controlling and recording temperature, cycle times, flow rates, pressure, etc., to ensure compliance with the specifications of the final product.

The production control is carried out through the analysis of physical samples collected in the different manufacturing batches, later carrying out, depending on the requirements of the pellets, the following analyses and tests:

• Rheological analyst by extrusion • Density • CIELAB colour • Shore A hardness // Shore D hardness • Traction control • Breaking stress control • Impact control • Vicat temperature control •

In addition, if needed we have the collaboration of different national and international technological institutes and external laboratories, to carry out more specific tests at the request of our clients.
