About Ken – Mold Engineering, Mechanical Design & Injection Molding Experience

I am Ken, the author of this engineering blog. My background covers mold making, mold design, tooling engineering, product mechanical design, injection molding, manufacturing process review, and engineering team management.

Before becoming a mechanical engineer, I spent several years in the mold and tooling industry. I started as a mold maker, moved into mold design, and later worked as a mold engineer. This experience helped me understand how product design, mold structure, injection molding, manufacturing cost, quality, and mass production risks are connected.

In 2016, after an organizational restructuring at my previous company, I changed my career direction and became a mechanical engineer. At the same time, I also took on the role of Mechanical Engineering Manager. This transition was challenging, but it helped me connect hands-on tooling experience with product mechanical design and engineering team management.

My practical experience includes plastic part design, DFM review, mold design review, MoldFlow analysis, injection molding defect analysis, tolerance stack-up, surface treatment processes, supplier communication, and cross-functional project coordination.

This blog shares practical engineering knowledge based on real product development and manufacturing experience. I write about engineering materials, product mechanical design, injection mold design, injection molding, manufacturing processes, surface treatment, and engineering software.

This blog is especially useful for mechanical engineers, product designers, mold designers, tooling engineers, injection molding engineers, manufacturing engineers, quality engineers, project managers, and beginners who want to understand the connection between design and manufacturing.

Many engineering problems are repeated across different projects and teams. Through this blog, I hope to help readers reduce avoidable mistakes, improve DFM thinking, communicate better with suppliers, and make better design decisions before problems appear in production.

A good engineer solves problems,A good engineering manager helps the team solve problems together. My goal is to continue sharing practical engineering knowledge that helps others design better products, avoid repeated mistakes, and connect product design with real manufacturing experience.
