表格
| Type | Working Principle | Core Advantages | Main Limitations | Typical Applications |
|---|---|---|---|---|
| Conventional Vacuum Thermoforming Machine | Heated & softened sheet is drawn onto mold surface purely by vacuum suction (0.07‑0.09 MPa). | Simple structure, low operation threshold and low investment; suitable for simple‑geometry articles. | Limited forming depth (≤150 mm); incapable of complex curved or deep‑draw parts. | Electronic component trays, thin blister packs, flat‑type packaging. |
| Positive‑Negative Pressure Integrated Forming Machine | Combines vacuum suction and compressed‑air pressure (0.4‑0.5 MPa) for sophisticated deep‑draw forming | Forms complex curved surfaces and deep‑cavity parts (depth up to 250 mm); compatible with eco‑friendly materials; supports independent zone temperature control. | Higher unit price and sophisticated technology. | Automotive interior parts, deep‑draw food containers, pharmaceutical trays. |
| High‑Speed Servo‑Driven Thermoforming Machine | Servo‑motor sheet‑feeding system combined with multi‑station layout for high‑speed high‑precision forming. | Extremely high productivity (220‑480 cycles/h); forming tolerance ≤0.1 mm; fine temperature control with 54 solid‑state power regulators. | Highest capital investment (300 000‑600 000 CNY); designed for mass standardized production. | Pharmaceutical blister inserts, supermarket food trays, beverage cups and other high‑volume articles. |
Multi‑station integrated machines represent the mainstream trend for high‑end thermoforming equipment. They integrate heating, forming, punching, trimming, stacking and counting into one fully‑automatic workflow, delivering finished parts directly from raw sheets and greatly boosting efficiency and automation level.
Core Technical Specifications: Key Indicators for Equipment Selection
After confirming machine type, define proper specifications with following critical parameters:
Forming Area (mm × mm): Core parameter reflecting machine capacity, defines maximum part footprint. Common sizes: small‑size 420×300 mm; medium‑size 710×850 mm; large‑size 820×650 mm. Select with adequate margin beyond actual part dimensions.
Forming Depth (mm): Maximum achievable part height, critical for deep‑cavity articles. ‑ Conventional vacuum thermoformer: ≤150 mm ‑ Positive‑negative pressure former: above 250 mm ‑ Deep‑draw articles require machines equipped with secondary stretching function.
Production Speed (cycles/h or cycles/min): Key productivity metric. Conventional machines: approx. 8‑32 cycles/min. High‑speed servo machines: 220‑480 cycles/h (≈4‑8 cycles/min, multiple parts per cycle). Always evaluate real output together with cavity count.
Sheet Thickness Range (mm): Processable sheet gauge determining application scope. ‑ Thin‑gauge thermoforming: 0.15‑2.0 mm for packaging articles. ‑ Thick‑gauge thermoforming: 1.0‑8.0 mm and above for home‑appliance liners, automotive interiors. ‑ Sheets over 1.5 mm require custom heavy‑duty oven and high‑pressure forming system.
Heating Power (kW): Determines heating capability, especially vital for thick sheets and hard‑to‑form materials. ‑ Easy‑to‑form grades such as PVC, PS: 10‑22 kW. ‑ Challenging grades such as PP, PET: ≥32 kW with infrared heaters. ‑ Large multi‑station machines: 150‑185 kW.
Vacuum‑System Parameters: Vacuum‑pump displacement (m³/h) governs evacuation speed and forming efficiency. ‑ Small‑size machine: 100 m³/h. ‑ Large‑size machine: ≥160 m³/h. ‑ Required vacuum level: ≥0.07‑0.09 MPa.
Applicable Materials: Thermoplastic sheets including PVC, PET, PP, PS, ABS, HIPS, PLA. High‑end units process eco‑friendly grades such as PLA, CPET.
Selection Guidelines
Follow clear logic for thermoforming‑machine selection:
Determine machine type according to finished‑part requirements ‑ Simple flat‑packaging & low‑volume production: conventional vacuum thermoformer. ‑ Complex curved geometry, deep‑cavity articles or eco‑friendly materials: positive‑negative pressure integrated former. ‑ Mass‑produced standardized articles (pharmaceutical inserts, food trays): high‑speed servo‑driven thermoformer delivers optimal efficiency.
Set specifications by part dimensions: Match forming area and forming depth to product length, width and height.
Configure heating system by material grade: Select heating power and temperature‑control accuracy for PVC versus PP / PET. High‑end infrared ceramic heaters achieve temperature tolerance ±1 ℃.
Match speed and automation to output targets: For high‑volume production consider multi‑station integrated machines combining forming, punching, trimming and stacking.
Plan auxiliary‑equipment matching: Complete production lines require supporting presses, heat‑sealers, high‑frequency machines and edge‑folding machines.
