Step 1: load parts
First step: the upper and lower products are placed together on the lower nest, and there are some moved blocks on both sides of upper and lower nests, to prevent the product from being deformed and cannot be placed in the nests.
Step 2: pre-positioning
Step 2: Manually move the two positioning blocks in the direction of the arrow, to clamp the lower product, while positioning the upper product on the lower nest.
Step 3: Clamp upper part
The third step: the upper and lower tools are pressed together, both parts are shaped, and the upper welding tool clamp will fix the upper part, and then start to welding.
