Marlan Tool builds close-tolerance parts and custom tooling: plastic injection molds from simple prototypes to complex multi-action and unscrewing molds, progressive dies, fixtures, gages and spare tooling. The shop runs high-speed 3D vertical machining centers with hard milling, high-speed 3D graphite mills, CNC lathes, wire and CNC ram EDM, close-tolerance surface grinding including carbide grinding, and full mold maintenance and reconditioning.
It is a shop with the capability to make almost anything in the building. The one thing it was buying outside was the mold base — and paying for that decision twice.
The Problem
A finished mold base is a convenience purchase. It arrives as one part number, one invoice, and one lead time. For a shop quoting competitive injection mold work, that lead time was 16 weeks — and it sat on the critical path of every job that needed one.
The total cost of ownership was worse than the invoice. A finished base carries the supplier's machining margin, its scheduling buffer, its freight and its risk premium. And because the base is ordered to a specific mold, every engineering change after release becomes a supplier conversation rather than a shop-floor decision.
The Technical Challenge
Building a base in-house is not a matter of buying a plate and drilling holes. A mold base is a system: plates, guide pins and bushings, return pins and springs, ejector plates, support pillars, locating rings, and the fit relationships between them. Get the guide-pin fit or the plate thickness wrong and the mold runs poorly for its entire life.
The real constraint was knowledge and availability, not machining capacity. Marlan already had the machines and the people. What it needed was a source for the individual components, dimensionally correct, in quantities that made sense for a shop building bases in batches rather than one at a time.
How Tooling Components Solved It
- Decomposed the base into its component families — plates and their thickness options, guide pin and bushing sets by size and fit class, return pin and spring combinations, ejector hardware, support and locating components.
- Supplied the components individually, so Marlan could buy to a build schedule instead of to a single finished assembly.
- Enabled stocking — components on the shelf mean a base starts when the job starts, not when a purchase order clears.
- Kept the specifications standard so the shop builds to known fits rather than re-engineering each base.
The Result
- 16 weeks of lead time removed from the mold build schedule. The base is no longer the long pole.
- Significant upfront cost savings versus the finished-base TCO, because the supplier's machining margin and scheduling buffer are no longer in the price.
- Components stocked on hand, so the shop builds molds at its own pace.
- Engineering changes handled in-house, on the shop's schedule.
The Pattern
Any shop that buys a finished assembly because it is simpler is buying lead time it cannot see. The alternative is not "make everything" — it is buying the components at the right level of assembly, standardizing the fit relationships, and holding stock on the items that gate the schedule.
Where Tooling Components Fits
Tooling Components supplies mold bases and mold components, ejector sleeves and pins, guide pins and bushings, die springs and gas springs, punches and dies, and drill bushings — the individual parts that let a shop build and repair tooling on its own schedule. If a finished assembly is costing you a month of lead time, we will break it into components and price the build.
