Fluctuations in raw material market faster, too late to timely updates on the site, please contact us, business phone: 18025226493, fixed with our utmost sincerity and build bridges of mutual cooperation of the company operating the nylon brand: DuPont PA6, Japan's Mitsubishi PA6, US Schulman PA6, US liquid nitrogen PA6, Japan Ube PA6, Taiwan Zig Sheng PA6, Toray PA6, Taiwan's Nanya PA6, BASF PA6, PA6 Baling petrochemical, etc. applications:
Industrial production in the pan used to make bearings, gears, cams, bevel gear, a variety of rollers, pulleys, pump impeller, fan blades, worm gear, propellers, screws, nuts, washers, high pressure seals, oil seal , oil containers, cover, hose, cable sheathing, shearing machine pulley sets, Shaper slider, and electromagnetic distribution of seats, cold Chen equipment, gaskets, bearing cage, cars and tractors on the various pipelines, piston , ropes, belts, industrial equipment, textile machinery zero fog materials, as well as commodity and packaging films.
Since PA6 is easy to absorb moisture, so the drying process with particular attention to, if the material is packed in waterproof material supply, the container should be kept closed. If the humidity is greater than 0.2%, it recommended drying at above 80 ℃ hot air for 16 hours If the material has been exposed to air for more than eight hours, it recommended temperature of 105 ℃, 8 hours of vacuum drying.
Melting temperature: 230-280 ℃, for enhancing the variety of 250-280 ℃.
Mold temperature: 80-90 ℃ Mold temperature is significantly affected cleanliness, and cleanliness also affect the mechanical properties of plastic parts for the structural components of the degree of crystallinity is very important, it is recommended that the mold temperature is 80-90 ℃ for... thin-walled, plastic parts process also recommended longer administration of the higher mold temperature. increasing the mold temperature increases the strength and stiffness of plastic parts, but reduces the toughness. If the wall thickness is greater than 3mm, it recommends the use of 20-40 ℃ low-temperature mold for glass fiber reinforced materials mold temperature should be greater than 80 ℃.
Injection pressure: Generally between 750-1250bar (depending on material and product design) Injection speed: high speed (for enhanced material is slightly lower)
Runners and gates: For PA6 solidification time is very short, the gate location is important aperture should not be less than 0.5 * T (where T is the thickness of plastic parts) If you use the hot runner, gate size should be less than. normal flow of small, because the runner can help prevent premature solidification of materials. If the minimum diameter dive gate, the gate should be 0.75mm.
PA6 in industrial applications:
Glass fiber reinforced polyamide material can be added glass content in the range of 5-60% depending on the characteristics of the product requirements, these materials have good strength, heat resistance, excellent impact resistance, good dimensional stability and low . warping, etc. in order to meet industrial requirements, reinforced polyamide material should meet the following requirements:
1). Excellent strength and durability, excellent rigidity and heat resistance combined
2) Excellent color performance, the perfect surface appearance, can be applied to complex structures forming, and help developers design and development of new styling products
3) Good workability, excellent flowability and thermal stability of the material processing conditions are more relaxed, so that miniaturization of injection molded parts
4) high thermal stability, can not hang up to 270 degrees in the wave soldering tin;
Edit this paragraph in the application of daily necessities
Glass fiber reinforced polyamide material with good dimensional stability and low warpage, solder and paint, easy to spray, can be had for ultrasonic welding, materials, good gloss, can be dyed a variety of bright colors, in order to meet the industry terms of product requirements, reinforced polyamide material should meet the following requirements:
1) strength and durability, excellent rigidity and heat resistance combined.
2) Optimized component design, excellent color performance, the perfect surface appearance, can be applied to complex structures forming, and help developers design and development of new styling products.
3) Good workability, excellent flowability and thermal stability of the material processing conditions are more relaxed, so that miniaturization of injection molded parts.
