Step ten: Proofreading of design drawings
After the PVC pipe fitting mold drawing design is completed, the mold designer will submit the design drawing and related original materials to the supervisor for proofreading. The proofreader should systematically proofread the overall structure, working principle, and operational feasibility of the mold according to the relevant design basis provided by the customer and the requirements of the customer.
Step eleven: the countersignature of the design drawings
After the PVC pipe fitting mold drawing is completed, it must be immediately submitted to the customer for approval. Only after the customer agrees, the mold can be prepared and put into production. When the customer has a big opinion that needs to make major changes, it must be redesigned and then handed over to the customer for approval until the customer is satisfied.
Step twelve: The exhaust system plays a vital role in the quality of the PVC pipe fitting mold.
The exhaust methods are as follows: 1. Use the exhaust slot. The exhaust groove is generally located at the last part of the cavity to be filled. The depth of the exhaust groove varies with different pipes, and is basically determined by the maximum clearance allowed when the plastic does not produce flash. 2. Use the matching clearance of cores, inserts, push rods, etc. or special exhaust plugs for exhaust. 3. Sometimes in order to prevent the vacuum deformation caused by the ejection of the PVC pipe fittings, it is necessary to design a vent insert
