I need to select a mould supplier for a PET bottle to be made via stretch blow molding. I have received quotations from various suppliers ranging from X to 3X. I need answers to the following questions:

1. How do you compare and decide between various mould quotations when all claim to be meeting all your technical requirements?

2. What else besides form cavities, neck plate, bottom base and guide should be included in the scope of supply?

3. What are the wear parts and consumables for a stretch blow mould?

4. What performance guarantees and after sales service can reasonably be demanded from a mould supplier?

I would greatly appreciate responses from the experts in this area.

Salam,

Compare between quotation is not easy task. Its up to relation and confidence. you can try to get some confidence measure before ordering.You can visit them for their factories or workshop as well as demand their customer list ,so that u can contact them if they are satisfy with your supplier.
Yes it should be included if you do not have already.
All above three you mentioned.
Its up to your requirement. it could be 1 million shots or above, depend on what material is being used in mold and their surface treatment.

I try to explain but its more convenient is to have some quotation, I hope you get better know and wait for further replies on your conversation.
