Choosing the right wood-plastic door production line needs to consider many factors, the following are some suggestions:
1. Production demand assessment
Output requirements: Determine the output of the required production line according to market demand, order volume, etc. For large-scale production, it is necessary to choose a high-yield production line, which may be equipped with large extruders and efficient auxiliary machines; For small-scale production, equipment with moderate output can be considered to avoid excessive investment.
Product specifications and types: Specify the size, shape, style and so on of wood-plastic doors to be produced. Different production lines may be suitable for specific specifications, such as some good at producing large doors, some suitable for small doors; And if you want to produce a variety of types of doors, the production line should have good versatility and flexibility, by replacing the mold and so on.
2. Technology and process
Extrusion technology: common single screw extrusion and twin screw extrusion. Twin-screw extruder mixing plasticizing effect is good, extrusion output is large, more suitable for the processing of wood-plastic materials, to ensure uniform and stable product quality, such as the production of high-quality, complex structure of wood-plastic doors, the priority is to choose the production line of twin-screw extrusion technology.
Molding process: One step molding process is the raw materials directly in a group of equipment to complete mixing, extrusion molding, high efficiency, mixing plasticization, energy saving, suitable for PVC a class of plastic wood products extrusion molding processing, but the raw material formula, feeding device, mold and extrusion equipment requirements are high, need high technical level staff operation; The two-step molding process is first granulated and then extruded, although the process is increased, the equipment and process control requirements are relatively low, and it is often used for the production of PP/PE wood-plastic products. According to their own technical ability, production demand and cost of comprehensive selection.
3. Equipment quality and performance
Equipment structure and material: extruder screw, barrel should be made of high quality alloy steel, after special heat treatment process, with high strength, high wear resistance and corrosion resistance, to ensure long-term stable operation; Other parts of the production line, such as molds, setting tables, tractors, etc., should also use high-quality materials and advanced manufacturing processes to ensure that the structure is strong and durable.
Control system: The advanced control system can accurately control the temperature, pressure, speed and other parameters in the production process to ensure the stability and consistency of product quality. Such as the use of PLC control system, can achieve automatic operation, real-time monitoring and fault diagnosis, easy operation, high control accuracy.
Production efficiency: Investigate the work efficiency of each equipment in the production line, such as the extrusion speed of the extruder, the traction speed of the tractor, etc., the overall efficiency of the production line can produce more products per unit time and reduce the unit cost. At the same time, the equipment should have good continuous operation ability to reduce downtime and maintenance frequency.
4. Manufacturer strength and after-sales service
Manufacturer qualification and reputation: Choose manufacturers with good reputation, rich experience and professional qualifications. It can be understood by consulting the historical performance of the manufacturer, customer evaluation, industry reputation, etc., that the manufacturer with rich production experience has more advantages in equipment design, manufacturing and debugging, and can provide more reliable products and solutions.
After-sales service: Perfect after-sales service is an important guarantee for the normal operation of the production line. Including equipment installation and commissioning, training guidance, maintenance, spare parts supply and so on. Manufacturers should be able to respond to customer needs in a timely manner, provide professional technical support and solutions, to ensure that the production line in the use of the process of problems can be quickly resolved, reduce the impact on production.
5. Cost budget
Equipment price: According to their own budget to determine the affordable price range of equipment, but not only the price as the selection criteria, need to consider the quality of equipment, performance, after-sales service and other factors, to avoid cheap and buy poor quality or unsuitable production lines.
Operating costs: Consider the energy consumption, raw material consumption, maintenance costs and other operating costs of the production line. Choosing energy efficient equipment can reduce long-term operating costs; At the same time, understand the equipment's requirements and adaptability to raw materials to avoid increasing costs due to limited selection of raw materials.
6. Field visit and sample evaluation
Field visit: If conditions, to the equipment manufacturer field visit, understand its production scale, manufacturing process, quality control, etc., observe the actual operating status of the equipment, and communicate with the manufacturer's technicians and operators to obtain more intuitive information.
Sample evaluation: manufacturers are required to provide the production of wood-plastic door samples, check the appearance quality of the sample, dimensional accuracy, physical properties, etc., assess whether it meets their own requirements and market standards, through the quality of the sample can reflect the performance and production capacity of the production line to a certain extent.
