Design Philosophy
AIHOFEN’s products are designed with core principles of high precision, reliability, energy efficiency, and scalability, considering harsh industrial conditions and following full-life-cycle reliability standards to deliver stable, low-maintenance, cost-effective solutions.

Technical Principles

The core working principle of AIHOFEN’s positive and negative pressure thermoforming machines is based on thermal plasticization combined with positive-negative pressure forming. The complete workflow includes: 1. Servo-driven sheet feeding with automatic width adjustment and multi-zone independent temperature control heating to soften sheets to a plasticized state; 2. Negative pressure pre-suction to fit sheets to molds, followed by 0.5–0.8MPa positive pressure supplementation to enhance forming details, ensuring full shaping of deep cavities and ribs; 3. Precision punching, large-tonnage cutting, and automatic stacking to complete the production process.

Core Architecture & Innovative Design
The machines adopt a modular multi-station independent design, with each station operating in parallel without interference to improve production efficiency. Equipped with a CNC control system (superior to conventional PLC), they support 8-axis manual mold alignment and 500+ parameter storage for quick recall.

Comparison with Traditional Solutions
Compared to traditional single negative pressure machines, AIHOFEN’s combination of positive and negative pressure solves issues like underformed deep cavities and uneven wall thickness, increasing product qualification rates by over 15%. Unlike sequential multi-station machines, its parallel station design boosts production capacity by 30% while reducing power consumption by 20%.

Technical Advantages & Differentiation

Military-Grade Precision Forming
Supported by GJB9001C military-grade quality certification, the machines feature a ball cast iron mold platform with 0.03mm parallelism and ±0.05mm punching precision. This ensures consistent product wall thickness and detail integrity, reducing material waste by 10% and lowering production costs.

High-Efficiency Multi-Station Integration
The parallel process design of 3/4/5 stations, paired with servo-driven systems, cuts production cycle time by 25% compared to sequential machines. The energy-saving design further reduces power consumption by over 20%, delivering significant cost savings for long-term operations.

International Standards & Compliance Certifications

AIHOFEN’s thermoforming machines follow strict international standards, including GJB9001C military-grade quality management system and EU Machinery Directive (MD) & Electromagnetic Compatibility (EMC) Directive. The company holds a CE certificate, ensuring compliance with EU market access requirements, and can provide full sets of test reports and conformity documents upon client request.
