Injection Mold Steel Selection: P20, 718H, NAK80, S136, and H13
The best mold steel is not the hardest or most expensive grade. Selection should match resin, surface requirement, expected tool life, wear location, corrosion…

Everything you need to know, all in one place. Our Knowledge Base covers materials, manufacturing processes, design guidelines, tolerances, and industry standards — giving engineers, designers, and buyers the technical reference they need to make informed decisions.
Our knowledge base is organized into five core categories covering everything from raw material selection to final inspection standards.
The articles our clients and engineering partners turn to most often when planning a new product development project.
Materials
A practical comparison framework covering mechanical properties, cost, and processability across the 17 most common engineering plastics.
Tolerances
What tolerance level is realistic for your part geometry and material, and when to specify tighter-than-standard tolerances.
Design Guidelines
Recommended wall thickness ranges by material family, and how uneven wall sections lead to warpage and sink marks.
The best mold steel is not the hardest or most expensive grade. Selection should match resin, surface requirement, expected tool life, wear location, corrosion…
Gate design is not only about where plastic enters the part. Gate type and position shape the filling pattern, pressure transmission, weld-line location, packing,…
Draft angle creates clearance as a molded part moves away from the core or cavity. The required draft depends on pull direction, wall depth,…
Ribs and bosses should add function without creating thick local masses. Good design connects stiffness, fastening, draft, flow, cooling, ejection, and assembly instead of…
A tight drawing is not the same as a capable assembly. CTQ planning identifies the dimensions that truly control function, then connects those dimensions…
Quality documentation answers different questions at different stages: FAI shows whether initial production parts meet defined requirements; PPAP demonstrates that the production system and…
