• Plastic materials commonly used in vacuum forming medical equipment shells

  2023 / 09 / 17

  Plastic materials commonly used in the processing of medical equipment shells Medical equipment casings are mostly made of vacuum forming and are mostly made of ABS material, with many requirements for materials, including: 1. It should have good heating elongation, high height to diameter ratio (elongation ratio), and good elongation; 2. There are also requirements for tensile strength, impact strength, and pinhole resistance; 3. Products with composite requirements must have good thermal adhesive strength; 4. Good transparency and glossiness, which is in line with the aesthetic of medical equipment 5. Products used for food and pharmaceutical packaging should have non-toxic, odorless, or low odor requirements, even at higher temperatures; 7. Products with color printing requirements can undergo corona treatment, etc. Thermoforming is mainly used to produce thin shell products, with different types and sizes of products. The principle of selecting materials for thermoforming can only use plastic varieties that can be subjected to thermoforming processing. Under heating conditions, the elastic modulus and load-bearing capacity of the material rapidly decrease. However, in practical applications, determining whether a material is suitable for hot forming processing still requires specific consideration from the material's thermal properties, mechanical properties, and aggregated structure. In order to determine the material requirements, it is still necessary to conduct relevant experiments for operation.

• Application and production process of vacuum forming blister packaging

  2023 / 09 / 16

  Vacuum forming bliaster packaging products use a plastic processing process where flat plastic hard sheets are heated and softened, and then vacuum adsorbed on the surface of the mold. Vacuum formed products are widely used in the plastic packaging industry. A. The main advantages of vacuum forming blister packaging are: 1. saving raw and auxiliary materials, light weight, convenient transportation, and meeting the requirements of environmentally friendly and green packaging; 2. Able to Packaging any irregular products without the need for additional cushioning materials; 3. The packaged product is transparent and visible, has a beautiful appearance, is easy to sell, and is suitable for machinery Automated packaging facilitates modern management, saves manpower, and improves efficiency. B. Blister packaging products mainly include: bubble shells, trays, blister boxes, and synonyms include: vacuum covers, bubble covers, etc. C. The blister packaging equipment mainly includes: blister packaging machines, blister forming machines, punching machines, sealing machines, high-frequency machines, and folding machines. D. The packaging products formed by packaging can be divided into: card insertion, card suction, double bubble shell, half bubble shell, half fold bubble shell, three fold bubble shell, etc. E. The production raw materials for blister packaging mainly include PVC, PS, PP, PET, PETG, and environmentally friendly materials such as flocking, anti-static, and conductive.

• The difference between vacuum forming and thermoforming?

  2023 / 09 / 13

  Thermoforming and vacuum forming are both methods of processing plastic sheets to create 3D shapes. The main difference between these two methods lies in the process and the final product. 1. Process: In thermoforming, the plastic sheet is heated until it becomes pliable, then it is formed to the shape of the mold by using pressure or vacuum. In vacuum forming, after the plastic sheet is heated, a vacuum is used to suck the sheet onto the mold, forming the shape. 2. Precision: Thermoforming generally allows for more precision and detailed shapes compared to vacuum forming. This is because in thermoforming, the pressure can be controlled more accurately, allowing for more precise shapes and details. 3. Cost: Vacuum forming is generally cheaper than thermoforming. This is because vacuum forming uses less expensive equipment and can produce parts faster. 4. Material Thickness: Thermoforming can handle thicker materials compared to vacuum forming. This makes thermoforming more suitable for heavy-duty applications. 5. Final Product: Thermoformed products are generally more robust and have a higher quality finish than vacuum formed products. This is because thermoforming allows for better control over the material, resulting in a more consistent and higher quality product. 6. Applications: Thermoforming is often used for producing larger and more complex parts, such as car bumpers, refrigerator liners, and plastic pallets. Vacuum forming, on the other hand, is often used for simpler and smaller parts, such as packaging, trays, and display stands.
