What type of screw barrel is suitable for injection molding manufacturers
Commonly used screws in the market are No. 45 steel, 40cr steel (chrome plated), and 38CrMoAlA nitrided steel. If your product is +glass fiber. When using chrome plating, it will slowly fall off after about 3 months, and the color difference will appear. Nitriding is best. Stainless steel screw cannot be made of glass fiber. Generally, ordinary screws are used for nonspecial materials. Such as PC\PMMA\PA and other materials. barrel…
How much do you know about the causes of extruder screw wear?
Each plastic has an ideal plasticizing temperature range, and the extruder screw barrel processing temperature should be controlled to make it close to this temperature range. Granular plastic enters the barrel from the hopper and first reaches the feeding section. Dry friction will inevitably occur in the feeding section. When these plastics are not heated enough and melted unevenly, it is easy to increase the abrasion of the inner wall…
What are the cleaning methods for the extruder screw?
The working condition of the extruder that needs to clean the screw is generally to change the color or restart after the machine has black spots. There are two common methods: one is to wash with raw materials or nozzle materials, and the other is to directly pull the screw for polishing and cleaning.The method of drawing the screw affects the precision of the equipment. Pulling the screw for a…
