Importance of a Suitable Wall Thickness in the Production of Perfect Plastic Parts

A few considerations must be taken to determine the appropriate wall thickness of a plastic commodity; it must obtain an equilibrium of the proper product weight, carefully calculated design and reasonable financial allocation. For instance, a plastic product with thick walls allows more durability but it also has a greater likelihood of warping during the cooling stage of the manufacturing operation.

Among the design elements available in the plastic injection molding industry, wall thickness has the greatest influence on the overall quality, speed of manufacturing process, and operational cost of a product. Today, let us talk about its importance in the overall success of a manufacturing project.

The Perks of Uniform Wall Thickness

Although thicker walls provide added durability, there are still some perks to manufacture thinner walls. As a matter of fact, the longer the manufacturing operation, the more benefits can be acquired if wall thickness is kept uniform, light and thin. This is very true when it comes to manufacturing a belt buckle hook and loop.

This factor is also considered as very important whenever projects involved require a high volume of output. Implementing a suitable wall thickness in your plastic commodities allow for:

Wall thickness is not dependent to any limitations or constraints but, in most cases, the objective is to engineer the thinnest wall achievable while taking into consideration the product’s structural size, geometry, and necessities. The raw material qualities and flow behavior should also be taken into account by the moulding company during this crucial phase.

The Effects of Improper Wall Thickness

During the cooling phase of the manufacturing process, uniform wall thickness is essential. If some areas of the product are thinner than others, the area may be susceptible to twisting, warping, cracking, or collapse. That will certainly affect the appearance of your belt buckle manufacturing project.

A suitable wall thickness decreases the chances of residual stress and shrinkage of the finished product. If a uniform wall thickness is not viable, gradual thickness is a great option to take.

The appropriate wall thickness of a plastic product supports a uniform flow of raw materials through the molds which ensures an optimal injection molding process. Differences in wall thickness will cause the liquified raw materials to take preferential pathways which may lead to unwanted outcomes like weld lines, unbalanced filling, or air trapping.
