Hi Hawk,
Thanks for your quick reply and sorry for my bad english descriptions.
Let me go in details to explain your concerns.
1. PVC&CPVC are the materials that we use their welding rod(3mm,4mm) accrordingly to weld those plaques or "structure wall" up. In our production field, we addressed this production as "wet bench" program. As i stated before, most products we made are like tank, scrubber, tray so on. In addtion, those PVC&CPVC plaques are machined by our CNC center.
2. PP is polyproplene exactly, sorry for the skimble-scamble shortform i used. We weld PP materials as same method as rest, like PVC CPVC, PE. which means we use its welding rod to weld them together in order to match customer's assemble prints.
3. PVDF and Halar are both new projects we are handling now and they need higher temperature, rigid hygeian condition, safety ventilation system to maintain its welding quality.
Our welding tools are welding guns with hot air blower, please refer to my attached link for reference
