45-Ton Precision Stamping | Built for Small-to-Medium Volume Operations
For businesses new to aluminum foil container manufacturing, or established operators looking to add a dedicated line for custom and small-batch orders, sizing up equipment often feels like an unfair tradeoff. High-tonnage production lines carry heavy upfront costs and sit underutilized on smaller runs, while budget low-end machines struggle with consistent precision, break down frequently, and produce containers with ragged edges or uneven forming that won’t pass quality audits.
The AF-45AT fully automatic aluminum foil container line was engineered to close this gap. It pairs a 45-ton high-precision punch press with an SL750 servo feeder, SG-2 automatic stacker and scrap baling system to handle the full production cycle — from raw foil roll loading to neatly stacked finished products. It holds stamping accuracy to JIS Grade 1 standards, with all core electrical and pneumatic parts sourced from established, field-proven brands. The entry-level investment is approachable, yet the machine runs reliably enough for daily production and flexible enough to handle multi-SKU, small-batch orders. For anyone entering the foil packaging space or expanding capacity strategically, it’s a practical, cost-effective choice.
What the Complete Line Includes
Four independent, modular units work in sync, so you can service, upgrade or reconfigure each section without replacing the entire line.
1. 45-Ton High-Precision Open-Type Punch Press
Compact tonnage, but full-grade precision you can rely on
Despite its 45-ton rating, this press is built to the same structural standards as larger production models. Its integral cast steel open frame, motor-gear-crankshaft drive and symmetrical six-sided copper guide rails deliver JIS Grade 1 stamping accuracy, so finished containers come out with clean trim, consistent depth and uniform forming — no uneven crimping or shallow draws from one stroke to the next.
- 450kN (45-ton) nominal force with a 3.5mm nominal force stroke, more than enough for standard shallow-draw containers and foil trays
- 240mm slide stroke and 480mm maximum die height, compatible with most standard container dies on the market
- Adjustable stroke rate from 50 to 78 strokes per minute, so you can dial in speed based on forming difficulty and balance output with quality
- 450mm throat depth and an 800×900mm worktable, with plenty of room for die setup and maintenance
- 7.5kW main motor keeps energy consumption reasonable for daily operation
Proven brand components for less downtime
Nothing derails delivery schedules like unplanned breakdowns. Every critical part on this press comes from widely recognized, serviceable brands:
- Main motor: SIEMENS (Germany) for steady power and long service life
- Secondary-drop safety: OMRON (Japan) for dependable operator and die protection
- Duplex solenoid valve: TACO (Japan) for fast, consistent pneumatic response
- Hydraulic overload protection: KingAir (Taiwan) for instant pressure relief if a jam occurs
- Wet clutch (Japan) for smoother, quieter running and longer wear life compared to dry clutch designs
- Seals: NAK / Halsen (Taiwan) to minimize oil leakage issues
- Upsized balance cylinder and frequency converter for added stability during continuous runs
2. SL750 Servo Aluminum Foil Feeder
Smooth, accurate conveying with no slippage or drift
Feeding precision has a direct impact on material waste and final product yield. This servo-driven feeder uses an ABB inverter paired with SIEMENS / Mitsubishi PLC control for steady, predictable material delivery.
- Handles foil rolls up to 750mm wide and 1000mm in unwinding diameter — larger rolls mean fewer changeovers and less downtime
- Feeding length adjusts steplessly from 1mm to 9999mm, with ±0.2mm positioning precision for tight nesting and minimal trim scrap
- Feeds at 0–150m/min, automatically matched to the press rhythm so material never piles up or gets pulled too tight
- 250mm of lateral and height adjustment makes die changeovers fast and straightforward
3. SG-2 Automatic Stacker
Hands-off collection saves labor and keeps parts clean
Manual picking and stacking is slow, leaves fingerprints, causes denting, and creates food-safety concerns. This stacker automates the entire collection process cleanly and consistently.
- Automatically conveys, counts and stacks containers — full stacks discharge ready for packaging, with no hand contact
- Available in single-channel or dual-channel setups: single-channel for containers up to 600×350mm, dual-channel for simultaneous 250×350mm production at higher throughput
- Stacks up to 500mm high (up to 120 pieces per stack) to cut down on material handling
- Stacks at up to 60 pieces per minute, fully matched to press output with no bottleneck
- Discharge height adjusts from 900–1200mm to fit different packing station layouts
- SIEMENS PLC + Weinview touchscreen for intuitive setup and straightforward operation
4. Scrap Recycling & Baling System
Automatic trim handling for a tidier workshop
Foil trimmings from stamping are pulled away by suction and compacted into dense bales in the hydraulic baler. You won’t need dedicated staff sweeping up scrap all shift, the shop floor stays cleaner, and compacted foil scrap carries higher recycling value — a small but steady savings that adds up over time.

Who This Line Works Best For
Startups and new market entrants
Get JIS Grade 1 precision and full automation at a far lower entry cost than large-tonnage lines — enough quality and capacity to pass customer factory audits from day one.
Existing facilities with high-volume main lines
Run large, long-running orders on your primary lines, and shift small-batch, multi-SKU custom work to this one. You’ll avoid constant die changeovers that eat into high-volume production time.
Makers of standard shallow-to-medium draw containers
45 tons is more than sufficient for standard takeaway containers, tartlet cups, baking foil trays and disposable plates — with lower power use and better overall economics.
Small-to-mid factories cutting labor costs
End-to-end automation means one operator can manage the line and handle packaging, replacing several manual positions and delivering clear long-term labor savings.
Practical Advantages That Add Up
Strong ROI without overbuying
You only pay for the tonnage you’ll actually use, not oversized capacity that sits idle. You get a fully automated, Grade 1 precision line at a price point that makes financial sense.
Consistent quality customers notice
JIS Grade 1 stamping and trusted brand components mean uniform product quality run after run, with none of the batch-to-batch variation that frustrates buyers.
Easy to learn, fast to run
The touchscreen interface with clear parameter settings means regular line workers can operate independently after just a few days of training — no dedicated senior technician required.
Low maintenance, easy to service
Core parts are widely available, well-known brands, so replacement components are easy to source locally and repair costs stay predictable.
Customizable to your product mix
Slide stroke, die height, throat depth and table size can all be tailored to your specific product requirements — no forcing your parts to fit a one-size-fits-all machine.
Whether you’re launching your first foil container operation or adding a flexible workhorse to complement your existing high-capacity lines, the AF-45AT strikes a reliable balance of performance, affordability and ease of use. It delivers consistent, production-ready quality without the price tag of a heavy-duty high-tonnage system.
