Overview

A permanent mold designed for repeatability, ejection, and maintenance.

The permanent mold is developed from the alloy, geometry, gating, clamping, ejection, cycle, cooling, and expected level of automation.

Problems we solve
Increasing repeatability compared with expendable molds
Designing gating and ejection
Creating a manual, semi-automatic, or automatic system
Controlling closing and alignment
Producing industrial runs of technical parts
Variants

Types and scope.

Manual permanent molds

Operator-assisted operation and closing. Ideal for: Runs and parts suited to manual handling.

Semi-automatic permanent molds

Partial integration of movements or ejection. Ideal for: Repetitive processes that need better cycle time and ergonomics.

Automatic permanent molds

Architecture compatible with project-defined automation. Ideal for: Continuous production and specialized cells.

Permanent mold plates and components

Manufacturing or replacement of cavities, cores, plates, and auxiliary elements. Ideal for: Maintenance, modifications, and capacity expansion.

Gating and ejection systems

Elements that control feeding, solidification, and part removal. Ideal for: Optimizing the permanent mold casting process.

Workflow

How we work.

01
Part and alloy analysis

We review geometry, weight, material, volume, tolerances, machining, and finish.

02
System definition

We select a manual, semi-automatic, or automatic architecture, parting lines, cores, gating, and ejection.

03
Thermal and mechanical design

We evaluate masses, closures, guides, supports, handling, and auxiliary elements.

04
Manufacturing and assembly

We machine, fit, and assemble the permanent mold.

05
Testing and validation

We check dimensions, closing, ejection, and visual inspection within scope.

Keep in mind

Technical considerations.

Alloy and temperature

They determine mold material, coatings, thermal expansion, and service life.

Gating and solidification

Feeding must be defined with the actual process to reduce defects and ease gate removal.

Ejection

Draft angles, cores, shrinkage, and temperature determine the demolding system.

Automation

Actuators, sensors, and controls must be defined together with the cell and integration responsibilities.
