Richland PatternsEst. 1981

Patterns that pour right the first time.

Patterns, match plates and core boxes for sand casting foundries. Built in Richland Center since 1981, from your print, your model or the old pattern on your shelf.

  • Black marks core prints
  • Red marks surfaces to be machined
  • Red stripes on yellow mark seats for loose pieces

What hangs on our wall

PT

Sand casting patterns

Loose patterns and cope and drag pattern plates for green sand and no-bake molding.

 MP

Match plates

Both halves on one plate, registered tight, for high-volume molding lines.

 CB

Core boxes

Boxes for the cores that form the inside of a casting, matched to your core process.

 RW

Repair and rework

Worn tooling rebuilt and engineering changes cut in, so the line keeps pouring.

Every job rides a traveler

The same ticket follows your pattern from the first look at the print to the shipping dock. Nothing leaves until every operation is signed off.

Pick the material for the run

How many molds a pattern has to make decides what it is made of. Tell us the annual volume and we will recommend the one that pays off.

HardwoodPrototypes, one-offs and short runs.
Urethane tooling boardStable and fast to machine. Most production work.
AluminumLong runs and machine molding where wear matters.
CompositeRigid and stable, for large patterns that have to hold their shape.
Cast ironThe longest production runs and the hardest-working molding lines.
PlasticsDurable engineering plastics for patterns, core boxes and wear parts.
NylonTough and low-friction, for wear strips, bushings and sliding parts.
