Whether producing industrial strapping requiring superior strength and heat resistance or manufacturing flame-retardant decorative strips compliant with safety regulations, this production line delivers stable and reliable processing solutions to expand your product portfolio.
Customer Questions & Answers
Does producing reinforced PP (e.g., with glass fibers) and flame-retardant PP cause significant wear on the equipment?
Yes, such filled or reinforced materials cause significantly more wear on the screw, barrel, and die head than pure PP. This is precisely why we use 38CrMoAlA nitrided screws and alloy steel barrels—they possess extremely high surface hardness and wear resistance, specifically designed to handle such abrasive materials, significantly extending the service life of core components.
Are there any special process considerations when processing modified materials like flame-retardant PP?
Main considerations are two-fold: 1) Stricter Temperature Control: Additives like flame retardants may have a narrow processing temperature window, requiring more precise temperature control (the machine's ±1°C accuracy is suitable). 2) Corrosiveness: Some flame-retardant systems can be corrosive; our screw/barrel material and surface treatment offer better corrosion resistance. It's advised to consult the material supplier for optimal process parameters when first processing a new grade.
When switching from processing common PP to modified PP, do components need to be replaced?
Typically, no component replacement is required. The core structure of the equipment is universal. The key is setting new process parameters like temperature, pressure, and speed on the PLC according to the specific characteristics of the modified material (e.g., MFI, filler content). The hardware capability of the equipment already covers the processing needs of these materials.
