Customized Quality Assurance Machine Spare Parts Metal Service

• Mold Cavity Inserts: These are the inner parts of the mold that come into direct contact with the EPP beads during the molding process. They are usually made of high - quality steel and are designed to withstand high temperatures and pressures. Over time, due to wear and tear, these inserts may need to be replaced to ensure the accuracy of the molded products.
• Mold Seals: Seals are used to prevent steam and cooling water from leaking out of the mold. They are made of rubber or other sealing materials and are installed around the edges of the mold and at the joints of the steam and water channels. Worn - out seals can lead to inefficient molding processes and should be replaced regularly.
• Ejector Pins: Ejector pins are used to push the molded EPP product out of the mold after the cooling process. They are distributed evenly in the mold and are connected to the ejection system. Ejector pins can become bent or damaged during the ejection process, and need to be inspected and replaced if necessary to ensure the smooth ejection of products.

Steam System Spare Parts

• Steam Valves: Steam valves control the flow and pressure of steam entering the mold. They are crucial for maintaining the proper steam supply during the molding process. Over time, the valve seats and seals may wear out, affecting the accuracy of steam control. Regular maintenance and replacement of steam valves are necessary to ensure the stable operation of the steam system.
• Steam Pipes: Steam pipes transport high - pressure steam from the steam generator to the mold. They are made of heat - resistant and pressure - resistant materials. However, due to the long - term action of high - temperature steam, the inner wall of the pipes may be corroded, and the joints may leak. Inspecting and replacing damaged steam pipes in a timely manner can prevent steam leakage and ensure the normal operation of the steam system.

Cooling System Spare Parts

• Water Pumps: Water pumps are used to circulate cooling water in the cooling system. They ensure that the cooling water can quickly and evenly flow through the mold to cool the molded products. The impellers and seals of water pumps are prone to wear and tear. Regular inspection and replacement of water pumps can ensure the normal operation of the cooling system and the effective cooling of products.
• Cooling Water Pipes: Cooling water pipes connect the water pump, the mold, and the cooling tower. They are usually made of copper or plastic. Similar to steam pipes, cooling water pipes may also be corroded or blocked by scale, affecting the cooling effect. Cleaning and replacing cooling water pipes regularly can improve the efficiency of the cooling system.

Electrical System Spare Parts

• Control Switches: Control switches are used to control the start - up, shutdown, and operation of various components of the EPP molding machine. They are prone to electrical burnout and mechanical wear. Regular inspection and replacement of control switches can ensure the normal operation of the electrical system and the safe operation of the machine.
• Sensors: Sensors are used to monitor the temperature, pressure, and other parameters during the molding process. They provide feedback signals to the control system to ensure the accuracy and stability of the molding process. Faulty sensors can lead to incorrect parameter settings and affect product quality. Therefore, timely replacement of damaged sensors is necessary
