The table below clearly shows how length affects mold costs and product cost, along with some practical methods to control costs:
| Influencing Factor | Impact on Mold Costs and Product Cost | Methods to Control Costs |
|---|---|---|
| Mold Specificity | Increased length may require special molds, which have more complex structures and higher processing difficulty and costs. | Prioritize manufacturers' existing similar molds. |
| Material & Design | Increased length directly leads to higher material usage and weight, driving up material costs and subsequent processing (e.g., plating) costs. | Optimize the design while meeting performance requirements, such as adopting a "reduced shank" design (shank diameter smaller than thread) to reduce weight. |
| Production Process | Producing long screws may involve multi-step processing (e.g., multi-stage cold heading), requiring higher-end equipment. | Work closely with suppliers to loosen tolerances on non-critical areas without affecting performance. |
To control the costs of longer extension screws, you can focus on the following aspects:
Optimize Screw Design: Ensure that the connection strength and usage requirements are met, and evaluate whether a "reduced shank" design can be adopted (where the shank diameter under the head is slightly smaller than the thread diameter). This can effectively reduce the weight per piece and material consumption.
Increase Production Quantity: If the demand is large, mass production can significantly spread the mold cost per screw.
Consult Professional Suppliers: Look for manufacturers with experience in producing long screws. They may have molds for similar specifications or mature processes that can offer more cost-effective solutions.
