Q1: Can this notching tooling process stainless steel tubing instead of carbon steel?

Yes, the standard tooling adapts to both carbon steel and 304/316 stainless steel tubes. For high-hardness stainless steel materials, we can upgrade knife-edge hardness to reduce tool wear without extra structural modification.

Q2: Will repeated punching enlarge notching dimensional tolerance over usage?

No. Vacuum heat treatment eliminates internal stress and improves abrasion resistance. Under standard operating tonnage, dimensional deviation stays within ±0.005mm after 5,000 punching cycles.

Q3: Does the tooling need daily lubrication maintenance?

Only weekly hydraulic oil lubrication for mounting sliding parts is required. The notching die body adopts anti-wear treatment, needing no daily polishing maintenance.

Q4: What is the order quantity and production cycle?

MOQ for all standard and custom notching dies is 1 piece. We do not support independent sample delivery. The overall production cycle takes 15 to 25 calendar days, depending on customized die structural complexity.

Q5: What international shipping terms do you support?

We support FOB, CIF, DDP and EXW global shipping terms. Finished tooling adopts rust-proof export wooden box packaging with complete customs documents.

Q6: What is the after-sales warranty policy?

We provide 3-month industrial warranty under standard operating conditions. Damage caused by over-tonnage operation and abnormal installation is excluded from free warranty scope.

Q7: What advantages does ALAS have?

As an experienced ironworker tooling manufacturer, ALAS integrates independent R&D, machining and quality testing. We provide verifiable manufacturing data, inspection reports and one-stop after-sales service, avoiding middleman markup.
