Blister products are processed with plastic. The production principle of the product is to heat and soften the flat plastic hard sheet material, then adsorb it on the surface of the mold with vacuum, and then cool it to form. Blister products are widely used. It is mainly used in electronics and electrical appliances. Industry, food industry, hardware tools, cosmetics industry, toy industry, daily necessities industry, medicine, health care products, automobiles, stationery and other categories of industries.
The general process of plastic thermoforming:
Plastic Sheet – Cutting – Sheet Fixing – Heating – Forming – Demoulding – Cutting Edge – Finished Product
Material requirements for plastic forming:
1. Blister molding can only produce products with relatively uniform wall thickness (generally, the chamfer is slightly thinner), and cannot produce plastic products with widely different wall thicknesses
2. The wall thickness of blister molding is generally in the range of 1 to 2mm or thinner (the most commonly used thickness of blister packaging for small packages is 0.15 to 0.25mm)
3. The elongation of blister-molded products is limited to a certain extent. The diameter-depth ratio of blister-molded plastic containers generally does not exceed 1, and in extreme cases, it cannot exceed 1.5.
4. The dimensional accuracy of blister molding is poor, and the relative error is generally more than one percent.
