Injection molding short shots, the incomplete filling of mold cavities, can be due to several factors – from material viscosity to inadequate machine settings and suboptimal mold designs. The short shots not only injection molding defects; they also affect the quality, durability, and functionality of the final product.

It is also necessary to take into consideration how the plastic mold will be used. If it is for a one-time project, then a smaller size may be more cost effective. On the other hand, if the mold will be used multiple times, then a larger size may be necessary in order to avoid having to replace it frequently.

With all of these factors affecting the cost, it can be difficult to determine what is a “reasonable” price for a plastic injection mold. However, there are some general guidelines that can be followed.

Material is Too Viscous / Poor Plastic Fluidity: Short shots can occur when the chosen plastic material exhibits high viscosity or poor fluidity. In such cases, the molten plastic may struggle to flow smoothly into the mold cavity, leading to incomplete fillings.

Injection molding enables mass-producing plastic parts with consistency, detail, and efficiency. While a highly cost-effective process, developing an accurate budget requires evaluating numerous cost components. We’ll explore fixed and variable costs, quoting considerations, design strategies, tooling factors, and advice for minimizing overall expenditures without sacrificing part quality.
