A good casting starts with patternmaking that fits the process.
Pattern geometry must account for demolding, shrinkage, machining allowance, cores, gating and manufacturing method. Fundimoldes ties those decisions to hands-on casting and machining experience.
Types and scope.
Patterns that form the main geometry of the cast part. Ideal for: New developments, spare parts and defined runs.
One or more patterns mounted on a plate for repeatability and easier handling. Ideal for: Recurring production and structured molding processes.
Tools that form internal cavities or geometry the main mold cannot produce. Ideal for: Hollow parts or parts with internal passages.
Foam or other materials for specific geometries or processes. Ideal for: Special parts, low volumes or particular casting strategies.
Components and geometric criteria for feeding, filling and metal flow. Ideal for: Integrating the pattern with the casting process.
Technical data sheet.
Patternmaking for sand, gas-cured sand or permanent mold casting
To be validated based on geometry, mold type and casting process
Wood, composite boards, engineering plastics, foam and aluminum
Dimensional inspection, gating adjustment and demolding test
Actual capacity subject to technical validation based on geometry, weight, material, tolerances and process.
How we work.
We review geometry, material, volume, molding process and downstream machining requirements.
We define the pattern, parting, plates, cores, auxiliary systems and construction material.
We apply shrinkage, draft and machining allowance criteria based on the technical information available.
We machine, assemble and finish the pattern and its auxiliary components.
We perform dimensional inspection, a gating review and a demolding test within scope.
Technical considerations.
These must be defined according to alloy, casting process, geometry and subsequent machining.
Their location affects demolding, flash, mold complexity and part finish.
Internal cavities require evaluating removal, support, tolerance and behavior during filling.
Wood, composite board, plastic, foam or aluminum is selected based on volume, accuracy, expected life and process.
Why Fundimoldes?
Engineering, patternmaking, casting, machining, assembly, finishing, validation and after-sales support under one operation.
Every proposal is backed by a review of geometry, material, process, equipment and real-world conditions.
Drawings, data sheets, reports and inspections are included according to project scope.
Fundimoldes can manufacture, maintain, repair, modify and reproduce tooling components.

Common questions.
Do you make only the pattern, or the casting too?
Both are possible: patternmaking as a standalone service, or combined with non-ferrous casting and machining.
Can you copy an existing pattern?
Yes, through surveying, measurement, 3D scanning or reverse engineering, depending on the condition and accuracy of the original.
What materials do you use for patternmaking?
Wood, composite boards, engineering plastics, single-use foams, aluminum and custom combinations.
How is pattern service life determined?
It depends on the material, molding process, handling, production volume and maintenance.
From pattern to cast part.
Green sand, gas-cured sand and permanent mold in-house.
Metal tooling for repeat casting.
3D printing for casting patterns and prototypes.
Machining of patterns, plates and the cast part.
Reproducing cast parts from a sample.
