Overview of plastic product processing for medical device shell processing

Plastic Contract Manufacturing Company is a method of using thermoplastic plastic sheets as raw materials to manufacture various products under its high elastic economic conditions. The processing of medical device shells is a mature process with relatively strict requirements on materials, mainly including the following points:

1. Heating elongation: The material should have excellent heating elongation, a good height-to-diameter ratio, and good expansibility.
2. Tensile strength and impact strength: It is necessary to achieve sufficiently high tensile strength, impact strength and pinhole resistance.
3. Hot adhesive strength: For products with composite requirements, good hot adhesive strength must be possessed.
4. Transparency and gloss: The material should have good transparency and gloss to facilitate the display of the packaged goods.
5. Easy to handle: Waste packaging should be easy to handle.
6. Food and medical safety: If used for food and medical packaging, the material must be non-toxic, odorless or low-odor.
7. Color printing treatment: For products that require color printing, corona treatment can be considered.

Injection molding is mainly used to produce thin shell products. These products vary in type and size, usually with simple shapes, including cups, plates, lids, medical instrument housings, medical utensils and instrument housings. The wall thickness of the products is usually very small, and the sheet thickness is generally 1~2mm or even thinner, so the processing technology requirements are very high. Although the product area may be large, thermoformed products are usually half-shell, which will limit their design to a certain extent.

When selecting plastic products, it is necessary to determine the type of material based on the performance requirements of the specific application. Therefore, the principle of thermoforming material selection is to use only plastic materials suitable for thermoforming. Broadly speaking, all thermoplastics are suitable for thermoforming because their elastic modulus and load-bearing capacity decrease rapidly under heating conditions. However, in practical applications, whether a material is suitable for thermoforming requires comprehensive consideration of the material’s thermal properties, mechanical properties and aggregate structure.

In order to ensure that the material meets specific requirements, the most effective way is to manufacture experimental samples or reasonably estimate the optimal material thickness required for a specific part.
