Provided is a method for welding an accessory part made of a thermoplastic resin to a parison which is being molded into a tank body. The method includes steps of: forming the accessory part to include an annular portion having an annular shape and a plurality of projections each projecting from the annual portion in a radially inward direction; and pressing the annular portion and the projections into the parison to be welded to the parison. Also provided is a welding structure of a tank body made of a resin and an accessory part made of a thermoplastic resin and welded to a wall surface of the tank body. The accessory part includes: an annular portion having an annular shape; and a plurality of projections each projecting from the annular portion in a radially inward direction. The annular portion and the plurality of projections are welded to the wall surface.

A vacuum form tooling is configured for a press or vacuum lamination system. The vacuum form tooling comprises a negatively pressurized lower mold supporting at least one substrate element to be laminated or to provide at least one molding tool to be molded. The vacuum form tooling further comprises a negatively pressurized upper mold. The vacuum form tooling includes a clamping frame adapted to clamp a film portion to be laminated on the at least one substrate element or to be molded onto the at least one molding tool. Said clamping frame is moveable from a first position to a second position. In the first position, the clamped film portion can be sucked at least partially into the negatively pressurized upper mold. In the second position, the clamped film portion can be sucked for lamination on the at least one substrate element.

According to examples, a non-transitory computer-readable medium may have stored thereon instructions that may cause a processor to determine a compliance level that the transfer mold is to have when the transfer mold is fabricated, in which the compliance level is to cause the transfer mold to apply a predefined level of force onto the wet part while reducing a risk of damage to the transfer mold caused by the application of the predefined level of force. The instructions may also cause the processor to generate a three-dimensional (3D) model of the transfer mold to have the determined compliance level when the transfer mold is fabricated.
