Equipment Overview:

The semi-automatic parallel seam welding machine MD-100 produced by guangzhou MinderHightech is a shell and cap sealing equipment that integrates a parallel sealing machine and a glove box. Through vacuum baking and operation of the capping process in the glove box, the moisture and oxygen content in the shell can be reduced to meet the needs of high performance and high reliability.

This equipment consists of parallel sealing machine and glove box. The sealing machine completes the capping process of the tube shell, and the glove box provides a process environment with low oxygen and low water vapor content for the capping process. The parallel seam welding machine is placed in the operation box of the glove box. After the material is baked in the vacuum oven, it is transferred from the inner door of the operation box to the operation box. After the capping process is completed, it is taken out through the exchange box.
