Modified fiber PA66 is a high-performance engineering plastic that improves its mechanical properties and thermal stability by adding reinforcing materials such as glass fiber or carbon fiber to nylon 66. Let’s learn more about the production process, quality assurance measures, uses and precautions of modified fiber-added PA66.
1. Production process
The production process of modified fiber PA66 includes raw material preparation, compounding, crushing, granulation, injection molding and other steps.
(1) Raw material preparation: Raw materials include PA66 resin, glass fiber or carbon fiber and other reinforcing materials, additives, etc. Among them, PA66 resin needs to be heated and melted under high temperature conditions, and then mixed with reinforcing materials, additives, etc. in a certain proportion.
(2) Compounding: Send the mixed raw materials into the extruder for compounding. Under the high temperature and high pressure conditions of the extruder, the raw materials are melted and mixed, and formed into a continuous shape by extrusion.
(3) Pulverization: The compounded shape needs to be pulverized for subsequent granulation and injection molding.
(4) Granulation: The pulverized material is granulated by a granulator to form a granular material suitable for injection molding.
(5) Injection molding processing: The granulated material is sent to an injection molding machine for processing to form modified fiber-added PA66 products of various shapes and sizes.
2. Quality Assurance Measures
A series of quality assurance measures need to be taken in the production process of modified fiber reinforced PA66 to ensure that the quality and performance of the product meet the standards and customer needs.
(1) Quality control of raw materials: The quality of raw materials directly affects the performance of modified fiber PA66 products. Therefore, in the process of purchasing and using raw materials, quality control and inspection are required to ensure that the raw materials meet the standards and requirements.
(2) Production process control: The production process of modified fiber-added PA66 needs to control temperature, time, pressure and other factors to ensure that the quality and performance of material compounding and injection molding processing meet the requirements.
(3) Product inspection: Strict inspection and testing of modified fiber-added PA66 products, including size, appearance, mechanical properties, thermal stability, etc., to ensure product quality and performance Modified fiber-added PA66 attention matter:
The processing temperature should be controlled at 230-280°C. Too high temperature will cause the material to decompose, and too low temperature will affect the plasticity and melting of the material.
The mold should be made of wear-resistant and high-temperature-resistant materials to ensure the life of the mold and production efficiency.
The opening of the mold should be appropriately enlarged so that the fibers can be fully expanded to ensure the strengthening effect.
The fiber-reinforced material should be evenly distributed throughout the injection molding process without aggregation, so as not to affect the mechanical properties of the product.
The fiber-added product should be post-treated, such as cooling, heating, stretching, etc., to further improve the strength and toughness of the product.
Uses of modified fiber PA66:
Modified and fiber-added PA66 is widely used in the fields of automobiles, electronics, aerospace, and home appliances. Among them, the automotive field is one of the largest application fields of modified fiber PA66. Modified fiber-added PA66 is mainly used in the manufacture of body shells, instrument panels, seats, door panels and other components in automobile manufacturing. various requirements.
Precautions for modified fiber PA66:
When using modified fiber-reinforced PA66, attention should be paid to the storage environment of the material to avoid the influence of adverse factors such as moisture, heat, and direct sunlight.
During the production process, care should be taken to keep the material dry to prevent the material from being damp and affecting the quality of the product.
During the production process, attention should be paid to the operating specifications to prevent the temperature of the material from being too high or too low, so as to avoid affecting the thermal stability of the material.
During the storage and transportation of the product, measures such as moisture-proof, moisture-proof, and sun-proof should be taken to maintain the quality of the product.
Environmental protection should be paid attention to in production, and measures should be taken to prevent materials from polluting the environment.
Quality assurance measures for modified fiber PA66:
Selection of raw materials: Select high-quality PA66 as the base material, and at the same time require the quality of the fiber material to meet relevant standards to ensure the mechanical properties and appearance quality of the product.
Strict quality control: In the production process, the production process and production parameters are strictly controlled to ensure stable product quality.
Product inspection: In the process of product production, each batch of products is inspected to ensure that the products meet relevant standards and customer requirements.
Tracking service: For customer feedback, track and deal with it in time to ensure customer satisfaction and product quality stability.
Establish a sound quality management system: establish a quality management system, formulate standard operating procedures and quality control standards to ensure stable and reliable product quality.
Upstream and downstream products of modified fiber PA66:
The upstream products of modified fiber PA66 mainly include polyamide raw materials (PA66), reinforcing agents and additives. Downstream products mainly include auto parts, electronic product casings, aerospace components, etc.
Transportation and packaging of modified fiber reinforced PA66:
Modified fiber-added PA66 is usually transported in bulk or packaged. According to different customer needs, you can choose the appropriate mode of transportation and packaging. Normally, the modified and fiber-added PA66 can be packaged in 25kg/bag, 500kg/bag, etc., and different packaging methods can be customized according to customer requirements.
In general, modified fiber-added PA66, as a high-quality modified engineering plastic, has good mechanical properties and durability, and is widely used in automobiles, electronics, aerospace, home appliances and other fields. In the process of production and transportation, it is necessary to strictly control the quality, pay attention to environmental protection and operation specifications, so as to ensure the quality and reliability of the product.
