Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as shower seals, pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films,Label Holder, Price Holder, TPU Tube, and sheeting, thermoplastic coatings, and wire insulation.

This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel. The molten polymer is then forced into a die, which shapes the polymer into a shape that hardens during cooling.

Material

TPU, TPV, TPE, TPR, PVC, PC, PP, ABS, PE, POM, PMMA, HIPS, Nylon, PETG, PSU, PEEK, PEX, PPS, PERT, PTFE etc.

Tolerance Standard

We can make parts according to your tolerance requirements, if you do not have special requirements on the tolerance,our tolerance is according to the standard of SJ/T10628-1995 standards, class 3 from hard plastic, and SJ/T10628-1995 standards, class 6 for soft plastic

Surface Treatment

With plastic extrusion, the surface can be smooth or texture.

Process Flow Diagram

Once the order is confirmed, our engineer will start to design the mould drawing and mould making. Once the mould making is finished, we’ll make several pieces of pre-production samples for test, if the dimensions are correct, then we will send the samples to customers for final confirmation. If the test failed, we will modify the mould or adjust the molding parameter to make new samples, and test it again. Once the samples are approval by customer, we will purchase the raw material and making quality inspection. Then mixing material, molding and trimming, we will make many times of inspection during the production. Finally we will arrange the assembly and packing. After whole order is ready, we will send the packing list to customer to arrange the shipment.

Quality Control

NEWAY’s quality is 100% according to ISO9001 Standard. We seriously take care of the quality control from IQC to OQC, throughout each step of the production. Let us show you our quality control:

For raw materials, we’ll do the IQC in time. All materials are procured only from the verified suppliers, who have implemented and maintain certified quality management systems in their plants. With full certificates, such as RoHs, Reach, MSDS, FDA, LFGB, UL, EN549, BPA free, EN71, and so on;

For pre-production samples, we'll provide several pieces to our clients for assembly and function testing. We will seal the samples in time once they're approval.

For Bulk Production, we'll do the IPQCS & PQC (Multiple Sampling Inspection) during production and we'll do the FQC (Sampling Inspection) after deburr or breaking sharp edges. In order to timely find problems, solve problems, reduce defective products, reduce manufacturing costs.

After packing and assembling, we'll do the OQC (Sampling Inspection) to make sure the final goods are qualified.

Below you find find our inspection equipment for your reference.
