A:The main raw materials for the production of wood-plastic products are wood flour and plastic. Wood flour is usually made from wood processing leftovers, which is environmentally friendly and gives products a natural texture. Plastics mostly use polyethylene, polypropylene, etc., with good corrosion resistance and processing properties. Combined with the two, the wood-plastic products produced have the advantages of wood and plastic, such as waterproof, anti-corrosion, durable, etc., and are widely used in buildings, gardens and other fields.
A:The selection of suitable wood plastic door production line needs comprehensive consideration. First identify the output and product specification requirements, and then evaluate the technical process, such as extrusion and molding methods. Focus on equipment quality, including materials, construction and control systems. The strength of the manufacturer and after-sales are also key, and field visits are necessary. Combined with the cost budget, but also look at the quality of the sample, multiple comparison can choose the ideal production line.
We sincerely invite you to visit our factory and check out our WPC production machine project testing on site. During the visit, you will witness how the raw materials are transformed into high-quality WPC products through a series of processes. You can observe the efficient operation of the production equipment up close and feel our careful production of every detail.Visit time: 25 Sep - 02 Oct, 2024 Visit location: Qingdao Yongte Plastic Machinery Co., Ltd.
A:Extrusion molding of plastic profiles is to extrude the molten plastic through the extruder, and then through a specific mold and setting device, so that it is cooled and solidified into a plastic profile with a specific shape and size. This process requires precise control of parameters such as temperature and speed to ensure product quality. Widely used in building materials, automobiles, electronics and other fields.
A:There are many difficulties in the manufacture of wood-plastic composite hollow veneer fence profiles, such as poor material compatibility resulting in poor combination, difficult to control the hollow structure during extrusion, complex mold design and high precision requirements, surface veneer treatment process is difficult to achieve ideal results. The solution includes optimization of material formulation and pretreatment, advanced temperature and pressure control system and online monitoring, optimization of molds with simulation technology, selection of finishing materials and pretreatment, etc., to improve product quality and production efficiency.
A:Select the extrusion mold to produce a specific shape of PVC profiles, to consider profile shape size and tolerance, mold material and manufacturing process, flow and cooling design, experience and technical support, cost budget. We should cooperate with the supplier to test and debug the mold, and integrate multiple factors to ensure that the mold can meet the production needs and ensure the quality and efficiency of the profile.
