The dimensional accuracy control of Blister Boxes (Flocking) is essential to ensure the quality and suitability of product packaging. Here are some ways to control the dimensional accuracy of Blister Boxes (Flocking):
Mold Design and Manufacturing
1. Accurate mold size: When designing the mold of Blister Boxes (Flocking), it is necessary to make accurate calculations based on the dimensional requirements of the product. Considering the shrinkage rate and processing error of the material, the mold size should be slightly larger than the size of the final product to ensure that the required dimensional accuracy can be achieved after blister molding.
2. High-quality mold manufacturing: Choose a professional mold manufacturer to ensure the manufacturing accuracy of the mold. Use advanced processing equipment and processes such as CNC machining, EDM, etc. to ensure the dimensional accuracy and surface quality of the mold. The material of the mold should also have good wear resistance and corrosion resistance to extend the service life of the mold.
Material Selection and Control
1. Suitable blister material: Choosing the right blister material is essential to control dimensional accuracy. Different blister materials have different shrinkage rates and thermal stability. The right material should be selected according to the requirements of the product and the use environment. At the same time, ensure the stability of the material quality to avoid dimensional changes due to differences in material batches.
2. Material thickness uniformity: The thickness uniformity of the blister material directly affects the dimensional accuracy of the Blister Boxes (Flocking). When purchasing materials, materials with uniform thickness should be selected and strict quality inspections should be carried out. During the production process, the heating temperature and time of the materials should be controlled to ensure uniform softening and molding of the materials.
Production process control
1. Blister molding process: Blister molding is a key link in the production of Blister Boxes (Flocking). Controlling the temperature, pressure and time of blister molding can effectively control the dimensional accuracy of the product. Excessive temperature and pressure may cause the material to overstretch and become larger in size; while too low temperature and pressure may cause the material to be poorly molded and smaller in size. Therefore, it is necessary to optimize the blister molding process parameters according to the characteristics of the material and the requirements of the product.
2. Flocking process: During the flocking process, ensure the uniformity and thickness of the flocking. Uneven flocking may cause the product surface to be uneven and affect the dimensional accuracy. At the same time, the temperature and time of flocking should be controlled to avoid affecting the product size due to heat shrinkage or deformation during the flocking process.
3. Post-processing process: After the production of Blister Boxes (Flocking) is completed, some post-processing processes are required, such as trimming, punching, etc. In these processes, precise tools and equipment should be used to strictly control the processing dimensions to ensure the final dimensional accuracy of the product.
Quality Inspection and Control
1. Dimension Inspection: Establish a strict quality inspection system and conduct regular inspections on the dimensions of Blister Boxes (Flocking). Use precise measuring tools such as calipers, micrometers, three-coordinate measuring machines, etc. to measure the length, width, height and wall thickness of the product. Timely discover products with out-of-tolerance dimensions and make adjustments or rework.
2. Process Control: During the production process, real-time process control should be carried out. By monitoring the parameters of process links such as blister molding, flocking and post-processing, problems can be discovered and adjusted in time. At the same time, regular maintenance and maintenance of production equipment should be carried out to ensure the accuracy and stability of the equipment.
In short, controlling the dimensional accuracy of Blister Boxes (Flocking) requires comprehensive consideration and control from multiple aspects such as mold design, material selection, production process and quality inspection. Only through strict management and control can we produce Blister Boxes (Flocking) with high dimensional accuracy and stable quality to meet customer needs.
