Heavy tooling & multi-ton molds
Big steel engineered, cut and proved out before a lot is released — the programs where the tool is the capital and getting it wrong is expensive twice. See what a multi-ton injection mold costs.
Work Jack has done
Contract manufacturing programs Jack has run.
Shops that needed hands.
JCH Design & Manufacturing has tooled and run manufacturing programs for inventors and US companies in electronics, housewares, garden, sporting goods, food safety, pet products and pet doors, and private label.
Jack has tooled and run programs for these names as the tooling principal. The photographs below are the kind of work, not a named brand’s part.

Kind of work
Proof by the program.
Ask about your category. Jack will say what he has built in it. The tools behind these programs are photographed on the molds page.
Three markets have their own pages: protective cases, marine and boat parts and consumer products and retail.
Full electronics build-outs
Not a board bought in and dropped into someone else’s housing: PCBA, firmware-adjacent builds and finished device assembly, with the enclosure tooled alongside the electronics. More on PCBA and electronics assembly.
Health & food safety equipment
Industrial product programs where the measurement is the product — instrument boards, sensing and the housings around them, held to tolerance and documented.
Protective cases, including firearm & rifle cases
Molded parts, webbing and hardware brought together as a finished assembly, with the fit and finish held to the same standard as the function.
Sporting goods & soft goods
Seasonal and wholesale programs with repeat tooling — the relationship is the tool, not a single purchase order.
Consumer home & garden
Private-label and branded household goods taken into production, through packaging, barcode and carton compliance.
Specialty food packaging paths
Brand programs that need a compliant packaging route as much as they need a part — planned before the first run rather than after it.
Private label & FBA programs
Sellers who need a principal on the tool rather than an agent wall — someone who still answers when the tool has to move or be cut again. Scale is discussed on the call; no count is published here.
Photographs are from Jack’s own tooling and the factories he runs. They show the kind of work described, not a named customer’s part.
Copy / reverse-engineer
Sample, then tool, then lot.
Unnamed on purpose. The sequence is the claim. There are more photographs of the lots on the proof page.
The sample
Send the unit. A photograph is enough to start.
The tool
Jack engineers the steel from what you sent.
The lot
First article, then volume, under the same man.
What was on fire
Three kinds of rescue. No invented quotes.
The names above are real. The wounds below are the ones those programs actually look like. Ask Jack which one was yours.
The sample lied
Golden sample signed. Lot three did not match. His people stayed on the line — material, count, the shot — so the next container was the one you paid for.
The last toolmaker left
Demand was fine. Hands were not. Jack reverse-engineered the steel from the unit on the bench and ran the next season without you building a department.
The tool would not leave
The factory held the steel. Permission, not logistics. Jack audits, crates, re-qualifies. You keep the program.
Tool custody, across all of it.
Whatever the category, Jack designs, maintains, stores and moves the tools he is entrusted with — so the steel is ready when you need the next run, or ready to leave if you want it moved. Terms sit in the engagement, not in a promise. The mold-cost note covers who owns the tool, and who keeps it.
