How to Select Screw Materials for Adding High Glass Fiber Materials to Injection Molding Machines

Different materials have different requirements for the shape of the plasticizing screw in injection molding machines due to differences in their melting speed, heat absorption during melting, melt viscosity, water absorption, thermal stability, and other characteristics. Even for the same material, due to different products, different modifiers and fillers such as flame retardants, lubricants, glass fibers, inorganic minerals, etc. added to plastics, or different requirements for color mixing and melting homogenization, as well as different particle shapes when unmelted, all have different requirements for the screw. Special screws must be used for plastics with special properties (PC, PMMA, PA, LCP, PES, PET, PVC, CA, CP, thermosetting plastics, etc.), special products (transparent optical lenses, LCD light-emitting plates - light guide plates, bottle blanks, gears, connectors, etc.), or specific granule shape (powder, sheet) plastics, halogen-free materials.
Injection molding machine screw
Suggestion for screw use: Imported powder alloy fully hardened screw (all alloy)
Treatment process: Special overall full hardening treatment process is carried out.
Sealing strength: Above 10000psi
Alloy thickness: screw overall fully hardened alloy
Surface hardness: HRC60-68
P3 all alloy screw (super wear-resistant, corrosion-resistant, high-speed resistant, high-temperature resistant to 600 ℃, high-pressure resistant)
Smooth and non porous to reduce surface adhesion and degradation, meticulously treated for fine structure, effectively preventing glue accumulation, low shear design, and low heat generation. Generally, small and medium-sized diameters are used, and molding PC ABS+PC, PP-R, flame retardant ABS, etc. have good effects. It can also be used to shape general plastics and PMMA ordinary products.
Scope of application: All alloy screws are mainly suitable for all electric precision injection molding machines, adding high glass fiber LCP, PPS, PES, PA6T, PPA, PEEK, halogen-free materials, magnetic powder, iron powder, bakelite and other special, high-temperature, and high corrosion plastics; And PC, PMMA transparent materials. Forming of light guide plate lenses.
