Design Services
Precision Mold Design Delivered Fast
We provide accurate mold designs faster than ever using the latest CAD software and updated hardware. Our expert engineers deliver high-quality designs and innovative solutions, helping customers maximize production time and stay ahead in mold design and engineering.
Smart Tooling Solutions
Choosing the right tooling for your application depends on part size, complexity, design confidence, materials, lifecycle, and demand. The Design team will evaluate these factors to recommend the best solution. Interchangeable insert molds add versatility, while multi-cavity molds and hot-feed systems improve efficiency in high-volume runs. For small volumes or similar parts, MUD mold systems are effective. With costly materials, innovative tooling design can minimize waste and control expenses.

Injection Mold Design
DesEngin offers custom mold design services with 18+ expert engineers. We use CAD/CAM, 3D simulation, and DFMEA to ensure precise, risk-free molds. We work closely with clients to align mold specifications with product goals and manufacturing needs, backed by years of experience.


Single Cavity
Fast, precise injection mold designs for large parts—high quality, short cycles, lower cost.

Multi Cavities Multi Parts
We design multi-gap molds for high-volume production, maximizing injection press efficiency.

Multi Cavities Same Part
We design multi-gap molds for high-volume production, maximizing injection press efficiency.

Stack Mold
Stacked injection molding boosts efficiency with multiple cavities, doubling production output.

Unscrews & Undercut
Injection molded parts with threads require innovative mold release
solutions.

Blowing Mold Design
We provide single- and multi-cavity blow molds with precise cooling and thermal balance for stable, high-quality production. Our designs focus on optimal metals and processing at cutting and separation lines to ensure professional, accurate, and durable end products.

Injection Blowing Design
Blow-molded plastic products often need precise neck details like wall thickness and threading, which blow molding alone can't provide. That’s why injection-blow molding is used—either semi-automatic (two machines) or automatic (injection and blowing in one machine).
