진공 성형 공정에는 어떤 단계가 있나요?
The vacuum forming process is a straightforward yet precise method for shaping plastic sheets into functional products. Each step must be carefully controlled to ensure high-quality results.
The vacuum forming process involves clamping, heating, forming, cooling, trimming, and finishing plastic sheets to create shaped products for various industries.
Clamping
The plastic sheet is secured in a frame to prevent movement during heating and forming. The frame must be robust enough to handle the sheet’s thickness, typically ranging from 1 to 10 mm.
난방
The sheet is heated using infrared or radiant heaters to a pliable temperature, typically between 120°C and 180°C, depending on the material. Proper temperature control is crucial to avoid overheating or underheating.
형성
The heated sheet is stretched over a mold, and vacuum pressure (typically 28-30 inches of mercury) is applied to draw the plastic tightly against the mold, ensuring accurate shaping.
냉각
The formed part is cooled using fans or ambient air to solidify the plastic and retain its shape. Cooling time varies based on material thickness and mold design.
트리밍
Excess material (flash) is removed using cutting tools or CNC machines to achieve the final part dimensions. Precision in trimming is essential for part quality.
마무리
Additional operations like printing, assembly, or secondary machining may be applied to meet specific product requirements, such as branding or functionality.
Vacuum forming can only produce simple shapes.False
While best suited for relatively simple geometries, vacuum forming can create complex shapes with proper mold design and process control.
