Tinplate Cutting Loss Control

Key Points in Tinplate Cutting Loss Control

27 June, 2026 News

Tinplate cutting loss directly hits your margin. Every 1% waste on a food can line represents thousands of dollars per year. Consequently, can makers and stampers treat nesting and die clearance as profit levers. Here is where loss happens and how to cut it.

Where the Waste Comes From

Loss source	Typical waste	Fix
Poor nesting layout	15–25%	Optimize blank nesting software
Wrong sheet size	5–10%	Slit coil to blank width
Die clearance off	3–5%	Reset die to 10% of thickness
Edge trim	3–5%	Order mill edge vs cut edge
Surface defects scrapped	2–5%	Inspect incoming stock

Lever 1: Nesting Optimization

Blanks arranged poorly leave gaps. Consequently, nesting software packs circles and rectangles tightly. Furthermore, shared cut lines reduce trim. Good nesting raises utilization from 70% to 85–90%.

Lever 2: Order the Right Sheet Size

If you order a full 800 mm sheet and stamp 65 mm blanks, you lose 15 mm per row. Instead, slit coil to the exact blank pitch width. Consequently, edge trim drops from 10% to under 2%.

Lever 3: Die Clearance

Clearance between punch and die matters. For 0.20 mm tinplate, clearance runs 10% of thickness (0.02 mm per side). Too tight and the die wears fast. Too loose and burrs form. Consequently, measure burr height weekly and regrind on schedule.

Lever 4: Surface Defect Control

Scratches and rust force you to scrap blanks. Consequently, inspect incoming tinplate before feeding the line. Furthermore, keep the lubrication film intact. We ship C11000 / T2 Copper Plate PVC-film protected for the same reason.

Lever 5: Inventory Discipline

Overstocked tinplate rusts at the edges. Furthermore, mixed batches cause confusion. Consequently, use FIFO and store coils horizontally with VCI paper.
