Product Description PCB Wet Process Equipment Plug-in The plug-in is a critical wear part in PCB wet process equipment (e.g., developing, etching, plating systems). It supports and guides transmission shafts, protecting conveyor bridges from damage while ensuring smooth operation. Applications Key Features Developing/etching/plating machines Conveyor bridge support systems Shaft protection in chemical environments Wear chemical resistance: Suitable for acid/alkali conditions Self-lubricating: Reduces friction and energy loss Easy replacement: Modular design minimizes downtime Material options: HDPE (standard), PVDF/PEEK/PFA (special needs) Item Specification Material PP,UPE (standard), PVDF (acid/alkali-resistant), PEEK (high-temp), PFA (high-purity) Dimensions Thickness, groove width, center distance, inner diameter (customizable) Selection Wheel outer diameter determines plug-in center distance Compatibility Wet process conveyor bridges, chemical treatment equipment Main Product Company Profile Shenzhen Qixingyuan Machinery Equipment Co., Ltd. is a high-tech enterprise specializing in the research and development, production and sales of air knife systems and PCB horizontal line supporting equipment.

Company Advantage Our Certificate & Exhibition Packaging & Shipping FAQ 1. What industries are our gears, wheel discs, rubber wheels, brushes, and absorbent sponges used in? Can they be used in other industries? Our gears, wheel discs, rubber wheels, brushes, and absorbent sponges are only used in the PCB equipment manufac- turing industry, such as grinding machines, etching machines, developing machines, and glass washers. We are not sure if they can be used in other industries. 2. What industries are air knives used in, and what are their main functions? Air knives can be used in many industries, such as beverage bottle drying equipment, PCB manufacturing equipment, textile equipment, ultrasonic cleaning, and coating equipment. Their main functions are drying, cooling,dust removal, water removal, and air curtains. 3. Can air knives be customized? Yes, the length of PVC and aluminum alloy air knives can be customized, but the shape is molded and cannot be cust- omized. Stainless steel and titanium alloy air knives can be fully customized to the customer's specific length, width, height, and shape. The customer will need to provide a drawing of the key dimensions. 4.With so many air knife models, how do I choose one, and what is the most important factor in choosing one? a. The most important factor is the air source: are you planning to use a high-pressure blower or an air compressor? Most of our air knives are designed for high-pressure blowers, but we also offer air knives for air compressors. b. The material you need depends on your operating environment, such as whether it's humid, corrosive, or has other special requirements. c. The installation space you need depends on the air knife model you use. We offer over twenty models in various sizes. 5. Can brushes, sponge rollers, and rubber rollers be customized in size? The outer diameter of rubber rollers (within 20-70 mm) can be customized according to customer drawings. Absorbent sponges and brushes are commonly used in the PCB industry, and their length and outer diameter can be customized. They are also suitable for other industries. 6.Can the wheel discs, gears, and plug-ins/U-block be made of different materials? These ac
