Good afternoon to you and hope you are doing well and great. Further to your questions and here are the answers:
1) This type of takeout tong (DT 22) can be used to pick up hot glass bottles from the top crown of crown seal finish before mould open process. The take out tong alignment and setting must be precise and we think you’ll not have problem as your company has good HEYE IS machine. The bronze take out tong insert must be machined precisely to the profile of the top crown.
2) DT 22 is standard nickel alloy casting which is stronger, harder and withstand rough handling and any jammed up on forming process. It is standard and common casting which is lower price. You can use stainless steel or mild steel but the cost will be higher to machine from solid metal and hardness is lower than nickel alloy.
We hope to answer to your question correctly. We’ll provide plunger cooler drawings for approval soon. Thank you.
