Proof

Factory photographs of tools, lots and first articles.

Most manufacturing websites show a warehouse in a country nobody can name. These are Jack's own pictures, taken on ordinary working days between 2019 and 2021 — the tools, the presses, the boards and the parts. Captions describe only what is in the frame.

Lab results on file

  • Transit. Retail boxes on two programs Jack managed passed the ISTA 6-Amazon.com-SIOC ship-in-own-container test at TÜV SÜD (August 2023).
  • Materials. The plastic parts and coating on a household product from a Taiwan factory Jack works with passed California Proposition 65 screening for lead, cadmium, phthalates and BPA at TÜV SÜD.

A report summary is available to qualified buyers under NDA. ISO certificates will be listed here once the documents are in hand. Certifications and test reports ›

New frames from Jack

Jack sent these over in September 2026. Steel, the press, the board and the metal, from the factories he uses. Captions describe only what is in the frame.

Tooling and molds

The expensive, long-lived part of any program. Steel that gets designed, cut, proved out and then lives for years. The injection molds Jack designed have their own page.

Not everything is plastic and steel. Sewn and webbed goods run through the same program discipline. More on cut-and-sew manufacturing.

Finished metal and consumer goods

Programs Jack's people have run to a finished unit — hitch hardware and a drying rack. Not a stock catalog. Metal parts are finished on lines like the ones on the powder coating page.

Packing and freight

The part of the job most buyers forget until it goes wrong. The retail side is on custom packaging.

Blister cards and clamshells have their own page: blister and clamshell packaging.

About these photographs. They are unretouched apart from resizing and format conversion, and all camera metadata has been removed before publishing — including location data, which is not ours to share. A small number of Jack's original photographs are deliberately not shown here because people are identifiable in them; factory staff did not agree to appear on a marketing site. Captions describe only what is visible in the frame: no certification, client name or production figure is claimed on this page.
