Eleven years in Chinese manufacturing — five designing injection molds, two reviewing them, three designing complete products. I have sat on both sides of the drawing: the one who designs it, and the one who has to cut steel for it.
Send a STEP or drawing. You get a ranked risk list before tooling is committed — where the sink marks will be, which walls are too thin, where it will not eject.
Full part and assembly design: internal stack, 3D, 2D drawings, BOM. Designed with the mold in mind from the first sketch.
Mechanics, PCB and firmware in one unit that actually runs — so you can hold it before committing to a development program.
Most DFM reviews come from people who have never stood at a trial shot. I have — and I have written the correction that saved the mold.
Eleven years working with Chinese mold shops and injection plants. I know what a quote really means and where the schedule slips.
Annotated drawings, short screen recordings, written decisions. No timezone calls required — you get the thinking in a form you can forward to your team.
Internal stack: air duct, motor mount and vibration isolation, filter housing, magnetic nozzle. Taken from concept review through tooling to mass production.
Single-cell lithium pack, motor and spindle in a grip-sized volume, dust sealing at the spindle opening, button feel designed for high-volume assembly.
New dimming product designed to reuse existing tooling. Re-engineered the older model so new and old shared common parts, avoiding a new mold.
Five years of full 3D mold design — parting surface, core and cavity, cooling, ejection, gating — plus Moldflow analysis and trial-shot diagnosis.
A STEP file, a drawing, or even a sketch and a photo. No template needed.
Written scope, fixed price, delivery date. No discovery call required.
Annotated drawings and short recordings as the design moves. You see decisions, not meetings.
Source files, drawings, and a BOM you can send straight to a supplier.
No commitment, no sales call. If the review is useful, we talk about the rest. If it is not, you have lost nothing and learned where your part will fail.
