I. Differences in Raw Materials and Production Processes1. PVC Wood-Plastic ProfilesMain Raw Materials: Polyvinyl chloride (PVC) resin, wood fibers (or plant fibers such as bamboo fibers), fillers (e.g., calcium carbonate), and additives (stabilizers, lubricants, flame retardants, etc.).P Read More

In the PVC (polyvinyl chloride) processing technology, mixing technology serves as the first procedure in the production of PVC products and plays a crucial role. However, many enterprises often do not attach sufficient importance to the mixing process, leading to misunderstandings among workers reg Read More

In the selection of twin-screw extruders, "high torque" and "high speed" are often mistakenly regarded as core indicators of equipment performance. Many enterprises blindly pursue maximum parameters while ignoring the matching logic in actual production. In fact, the scientific ratio of torque to sp Read More

Even with the right extruder, WPC manufacturers often face production issues that affect product quality or efficiency. Below are 5 of the most common problems, their root causes, and step-by-step solutions—designed to help you minimize scrap and keep production running smoothly.1. Problem: WPC Prof Read More

When planning to produce wood-plastic composites (WPC) profiles—such as decking, fencing, or wall panels—selecting the right plastic extruder is critical to ensuring product quality, production efficiency, and long-term profitability. Many manufacturers overlook key factors that can lead to issues l Read More

In the operation of plastic recycling production lines, blades, filters, and sealing rings are high-frequency wear parts. Their replacement frequency and quality directly affect equipment efficiency, recycled material quality, and operating costs. Many enterprises experience over 30% reduction in we Read More

Odor in recycled plastics is a key obstacle restricting their high-value applications, especially in fields sensitive to olfactory experience such as packaging and home furnishing. Odors mainly originate from residual impurities (e.g., ink, pesticides), polymer degradation products (e.g., small mole Read More

I. Analysis of Raw Material Characteristics (Premise for Equipment Selection)1. Characteristics of Agricultural Filmso Mainly composed of PE (predominantly low-density PE), containing large amounts of impurities: soil (30%-50%), pesticide residues, crop straw, metals (steel wires in mulch films Read More

In the plastic extrusion molding process, temperature control is one of the core factors determining product quality. Whether producing pipes, films, or profiles, precise temperature parameter settings directly affect material plasticization, product mechanical properties, and production stability. Read More
