Generally speaking, customers engaged in the blister industry for many years have the ability to judge and choose the right blister machine to produce. But for most of the customers may need the assistance of the manufacturer to decide which specifications of the thick film molding machine, or even customers may only product samples or ideas, and then ask the manufacturer whether the machine can be produced, or which model is more suitable.
In general, important factors for selection include molds, products, types of plastics and production requirements, etc. Therefore, the following information must be collected or provided before making a selection:
Product external dimensions (length, width and height);
The wall thickness of the product;
The type and quantity of products to be used;
After obtaining the above information, you can follow the following steps to select the appropriate thick film blister machine:
1. The external size of the product determines the wellhead size of the machine. Select a small thick film machine when the forming area is less than 1.5 square meters, a medium thick film machine when the forming area is 1.5 to 3.7 square meters, and a large thick film machine when the forming area is more than 3.7 square meters, as described above in the classification of models.
2. If the wall thickness of the product is between 1.5-2mm and the product's tensile ratio (the ratio of height/length + the average size of width) is greater than 1, double-layer heating model should be selected; if less than 1, single-layer heating model should be selected.
If the product wall thickness is below 1.5mm, no matter how big the stretching ratio is, (of course, the stretching ratio of more than 1.5 products should not be done blister) choose single-layer heating model can.
If the wall thickness of the product is more than 2MM, single-layer heating model should be selected if the tensile ratio is below 0.5, and double-layer heating model should be selected if the tensile ratio is over 0.5.
3, according to the type and quantity of products to choose, such as the product is relatively single, the number of more, the annual output of more than 60,000-80,000 then choose double-work or multi-work model, such as heating molding synchronous type of blister machine, and blister mold choose aluminum alloy mold is appropriate; If the product specification is more, the single quantity is less, then choose sim-Position is advisable, and choose heating unit one control one, pressing frame and supporting plate can be adjusted, the model with convenient mold change is better, most of the blister molds use resin or electric wood as advisable.
