Thin wall mould

A. Professional thin wall mould manufacturer.

Thin-wall packaging parts are among the most demanding applications in the injection molding world. Thin wall mould are designed for plastic parts with the thickness is less than 1mm, and the projected area of the plastic part is greater than 50cm square. The wall thickness of the molded part is less than 1mm or 1.5mm.

Thin wall applications are more about speed than pressure. Faster plastic flow eases the filling of the part. Due to the fast running speed of thin wall injection mould, the cycle time can sometimes reach 4s. High-quality mold design and mold construction are the key factors for the success of injection molded thin-walled products, otherwise the mold will quickly break down.

We provide precision scientific training for process technicians and management personnel on thin wall forming. A professional technical team will help ensure excellent thin wall forming mold design and production processing. Having worked with a variety of clients within this specialist market sector for many years, we have assisted our clients to design and develop new and exciting plastic injection molded products specifically for the thin wall food packaging.

B. Thin wall injection molding application:

Thin-wall injection molding is not only suitable for lightweight food packaging. Through proper part design, analysis and hot runner system, it is also widely used in various injection molding industries, medical, etc., such as:

1. Food packaging

2. Plastic cover

3. Medical equipment

4. Plastic container and lid

5. Plastic packaging of consumer goods

C. Thin wall injection molding advantage:

One of the advantages of thin wall injection molding is that when the thickness is reduced, less material needs to be cooled. As the thickness is reduced, the molding cycle can be cut in half. The proper placement of the melt delivery device allows the hot runners and runners to not interfere with the shortening of the molding cycle, and the use of hot runners and sprue bushings helps to minimize molding cycles. It is easy to integrate design and assembly, shorten the production cycle, save materials, and reduce costs.

Specific requirements for thin-walled products:

1. High impact strength

2. Good appearance quality

3. Dimensional stability

4. Can withstand large static loads

5. The molding material should have good fluidity.

D. Key points of Thin wall molding design:

1. The wall thickness is small, but it must meet the product's impact strength, appearance quality, dimensional stability, and precision dimensional tolerances, and can withstand greater static load requirements.

2. The rigidity, impact resistance and manufacturability of plastic parts must be considered in the design process.

3. Since the thin-walled injection mold cavity is very narrow and the melt filling resistance is large, sharp corners should be avoided when designing plastic parts to reduce perforation.

4. Thin wall injection molding process uses higher pressure, which limits local shrinkage and allows thicker rib design.

5. When the wall thickness is less than 1.00mm, the rib can be as thick as the wall thickness.

6. Due to the small shrinkage of thin walled plastic parts, the drafting amount of ribs, bosses and edges should be increased.
