Mold&Moldings

Warpage and deformation of injection molded products are very troublesome. It should be dealt with mainly from the aspect of mold planning, while the adjustment effect of molding conditions is very limited. So, how do we deal with the warpage and deformation of plastic injection molded products?

 

1. When poor demolding causes stress and deformation, it can be dealt with by increasing the number or area of push rods and setting demolding slope.

2. When the residual stress is deformed due to the molding conditions, the stress can be eliminated by reducing the injection pressure, increasing the mold and making the mold temperature uniform, increasing the resin temperature, or using annealing methods.

3. The cooling method can be adjusted and the cooling time can be prolonged when the cooling method is not suitable and the cooling is uneven or the cooling time is insufficient. For example, the cooling circuit can be arranged as close as possible to the deformed place.

4. Regarding the deformation caused by the shortening of the molding, the mold plan must be revised. Among them, the most important thing is to pay attention to the common wall thickness of the products. Sometimes, as a last resort, the deformation of the product has to be measured, and the mold is trimmed in the opposite direction for correction. Resins with larger shortening rates are generally crystalline resins (such as polyoxymethylene, nylon, polypropylene, polyethylene and PET resins) than non-crystalline resins (such as PMMA resin, polyvinyl chloride, polystyrene, ABS resin, etc.) The deformation of AS resin, etc.) is large. In addition, because the glass fiber reinforced resin has fiber orientation, the deformation is also large.

The threaded thread internal thread and external thread of the threaded component, the thread shape of the threaded product is generally divided into standard thread, thread, trapezoidal thread, threaded tooth thread, arc arc

Thread and V-shaped thread. You can choose different purposes for different purposes, and you can choose serrated threads to meet your strength requirements. About the commonly used today

Bottles and cap screws can usually be fixed 1-2 times with a variety of bows.

 

Compared with metal, the strength of plastic is not high, plastic is generally softer, and the shape of plastic products should be more suitable.

Rod, other possible predictions will lead to the possible intensity of the mouse.

 

There are some ways to attack the product.

1. Direct molding during molding.

2. Use processing methods after processing.

3. The use of metal threaded inserts often requires reassembly and disassembly, as well as occasions suitable for mechanical strength.
