Pressure Forming Machines.
Roll-fed pressure forming machines for thin gauge packaging and deep draw containers. Machinecraft offers two pressure forming platforms: the AM Series for standalone forming and the FCS Series for integrated form-cut-stack production lines.
What is pressure forming?
Pressure forming adds compressed air (3-6 bar positive pressure) on top of the heated sheet during forming, in addition to vacuum from below. This produces sharper detail, tighter radii, and better surface texture than vacuum forming alone — creating parts that look injection-molded at thermoforming costs.
While vacuum forming relies solely on atmospheric pressure (approximately 1 bar) to shape the material, pressure forming applies an additional 3 to 6 bar of compressed air from above. This significantly increases the total forming force, allowing the material to replicate fine mold details, sharp corners, and textured surfaces that vacuum forming cannot achieve.
Pressure forming is particularly valuable for packaging applications where shelf appeal matters, automotive interior components that need a Class A surface finish, and any application where the formed part must visually match injection-molded quality without the associated tooling costs and lead times.
AM Series — Thin Gauge Roll-Fed Forming.
Standalone roll-fed forming machines for thin gauge packaging and containers. Available in vacuum-only (AM-V) and pressure forming (AM-P) configurations. Ideal for flexible production with lower initial investment.
AM-V (Vacuum Forming)
Roll-fed vacuum forming machine for thin gauge packaging and containers. Ideal for food trays, blister packs, and consumer packaging where vacuum forming provides sufficient detail.
AM-P (Pressure Forming)
Roll-fed pressure forming machine with vacuum and compressed air capability. Produces parts with high quality surface finish for premium packaging and deep draw containers.
FCS Series — Form-Cut-Stack Line.
Integrated roll-fed thermoforming lines that form, cut, and stack finished parts in a single continuous process. Designed for high-volume production of food packaging, trays, containers, and industrial packaging.
FCS Series
Roll-fed continuous pressure forming machine with integrated forming, punching, and stacking stations. Available in Eco (pneumatic), Pro (servo), and XL (high-speed servo) variants. Servo-driven spike chain indexing with ±0.3mm accuracy.
Key Specifications
How does the form-cut-stack process work?
The FCS process feeds a continuous roll of thermoplastic film through four stations in sequence: heating, forming, cutting, and stacking — producing finished, trimmed, and counted parts without manual handling.
Unwinding & Feeding
The thermoplastic roll is loaded onto the unwind station. Servo-driven spike chains grip the film edges and index it forward with ±0.3mm accuracy, ensuring precise registration at each station.
Heating
Sandwich infrared heaters (top and bottom) heat the film to forming temperature. Zone-controlled heating ensures uniform temperature across the full 600×900mm forming area.
Forming
A toggle press drives the mold into the heated film. Vacuum and/or compressed air shape the material against the mold. The toggle mechanism provides consistent forming force and speed across every cycle.
Cutting (Punching)
The formed web advances to the cutting station where a steel rule die or matched metal die punches out the finished parts with up to 60 tonnes of force. Clean, precise cuts with no secondary trimming required.
Stacking & Counting
Finished parts are automatically stacked, counted, and collected. The skeleton (trim waste) is wound onto a separate roll for recycling or granulation.
AM Series vs FCS Series — which machine do you need?
Both the AM Series and FCS Series are pressure forming machines. The AM Series is a standalone forming machine ideal for flexible production, while the FCS Series integrates forming, cutting, and stacking in one continuous line for maximum throughput.
| Factor | AM Series | FCS Series |
|---|---|---|
| Type | Standalone forming machine | Integrated form-cut-stack line |
| Forming Area | 500 × 600mm | 600×500 to 800×600mm |
| Integrated Cutting | No (separate station needed) | Yes (up to 60 tonne) |
| Integrated Stacking | No | Yes (automatic) |
| Forming Method | Standard press | Toggle press |
| Best For | Flexible production, lower volumes | High-volume packaging lines |
| Footprint | Compact (standalone) | Larger (integrated line) |
| Investment | Lower (forming only) | Higher (complete line) |
| Variants | AM-V (vacuum) / AM-P (pressure) | FCS 6050 (3/4 ST) / S FCS 8060 (3/4 ST) |
When should you choose pressure forming over vacuum forming?
Choose pressure forming when your application requires sharp detail, textured surfaces, tight radii, or an injection-molded appearance — especially for packaging with shelf appeal, automotive interior components, or medical device housings.
| Factor | Vacuum Forming | Pressure Forming |
|---|---|---|
| Forming Pressure | ~1 bar (vacuum only) | 4-7 bar (vacuum + compressed air) |
| Surface Detail | Moderate | High — rivals injection molding |
| Corner Radii | Rounded (3-5mm minimum) | Sharp (1-2mm achievable) |
| Texture Replication | Limited | Excellent — reproduces mold texture |
| Undercuts | Not possible | Possible with split tooling |
| Typical Applications | Structural parts, covers, panels | Premium packaging, automotive trim, medical |
| Machinecraft Machine | PF1-X Series (heavy gauge) | AM-P / FCS Series (thin gauge roll-fed) |
