Design for Manufacturability (DFM) at ASH Industries

At ASH Industries, we don’t just specialize in injection molding—we help you get it right from the start. Our Design for Manufacturability (DFM) consultation service evaluates your part design before production to identify potential molding challenges and opportunities for optimization.

Even a strong functional design may not translate efficiently into manufacturing. By reviewing your part early in the development process, our team can recommend targeted design improvements that reduce risk, improve performance, and lower overall production costs. This collaborative approach helps ensure your parts are both functional and efficiently manufacturable.

Without proper DFM considerations, plastic, metal, and silicone parts can develop costly and time-consuming defects, including:

• Warping and shrinkage – Uneven cooling or inconsistent wall thickness can cause parts to distort or fall out of specification.
• Sink marks – Thick sections cool unevenly, creating visible surface depressions.
• Short shots – Incomplete mold filling results in missing or unfinished features.
• Flash – Excess material escapes the mold cavity, requiring secondary trimming and adding cost.
• Poor surface finish – Air entrapment or improper cooling can lead to rough or inconsistent surface quality.
• Insufficient draft- Proper draft angles allow the part to release cleanly from the mold, helping prevent sticking, damage, and other defects. This can also require more complex tooling solutions and increase mold costs.
• Undercuts- Features that prevent a part from being removed directly from the mold may require side actions, lifters, or other specialized tooling, increasing mold complexity, cost, and maintenance requirements.

We work closely with your engineering team to analyze geometry, wall thickness, material selection, draft angles, and other critical design factors. When issues are identified, we provide practical, manufacturable recommendations that optimize your design without compromising functionality.

This proactive process helps streamline production and ensures your design is ready to scale.
