What is the effect of excessive clearance between screw and barrel? Influence of excessive gap between screw and barrel: 1. The gap between the screw and the barrel is too large, and the flow rate of the molten material during extrusion is unstable, and the product surface is prone to horizontal wrinkles. 2. The gap is too large, the extrusion melt pressure is unstable, so that the c
Reasons for maintenance of barrel screw of cone double extruder The barrel screw of the cone double extruder has its unique large feeding area, large compression ratio, the shear and mixing efficiency of the screw in the longitudinal and transverse directions of the material is higher, and the plasticizing ability is more excellent, so it is especially suitable for High calcium filled PVC powde
Introduction of the heating method and power of the screw barrel of the granulator In the plasticizing process of the injection molding machine, a large part of the screw barrel of the granulator mainly depends on the heating of the barrel. Pelletizer screw barrel heating method: Jane heating widely adopts the method of resistance heating, and uses thermocouples to achieve segmented tempe
Introduction to the types of barrel screw of bottle blowing machine The barrel screw of the bottle blowing machine is made of high-quality nitrided steel. The product is refined by processes such as tempering, qualitative, nitriding, fine grinding and polishing. The quality reaches the industry standard and solves the problem that the spraying bimetallic barrel is easy to crack. Shedding, stoma
Technical parameters of barrel screw of film blowing machine: Overall hardness: HRC58°-68° Nitriding depth: 0.4mm-0.7mm Straightness: 0.015mm-1000mm Screw diameter: Ф15-Ф360 L/D ratio: L/D=15-45 Screw types: gradual change, sudden change, wavy, barrier type, double screen type, cone type, split type, separate type, exhaust type, pin type, mixed type, double head, three head, m
Basic parameters and uses of full hard screw barrel Full hard screw barrel is a special screw barrel, which is made of imported full hard steel material, and undergoes a special processing technology, which is suitable for the requirements of high-abrasion processing products, ensuring the requirements of wear resistance and corrosion resistance. Basic parameters of full hard screw barre
Processing requirements of barrel screw Barrel screw processing technology requirements: (1) Technical requirements for barrel quality: ①The barrel is made of corrosion-resistant and wear-resistant alloy steel. At present, 38CrMoAl, 400 or 45# steel is mostly used in China. ② The cylinder blank should be forged to shape. ③The barrel should be tempered after rough machining, har
Design requirements of double alloy screw barrel The bimetallic screw barrel bimetallic process is a more commonly used process combination product with excellent corrosion resistance and wear resistance in recent years. It adopts HVOF high-speed spraying equipment to melt spray spray the surface of the screw to obtain a densely structured bimetallic screw. ; The bimetallic barrel adopts the me
