Let's start with your project requirements.

Large mounting area

Consider sets with widths determined by your project for the placement of multiple power modules.

Limited volume

Select height, fin geometry, and base structure based on available space.

Design optimized for airflow

Share your natural or forced convection requirements. Fin density and airflow are evaluated together.

BONDED SETS

Eight different sets. Structures and dimensions to suit your project.

PRODUCTION METHODS

Assembled sets and bonding.

Assembled profile sets

Profile elements are assembled to create a structure tailored to the project. The 1420 AS Set and 1426 AS Set are joined using a press-fit method without the use of studs. The connection structure of each family is evaluated according to its own technical drawing.

Bonding solutions

Thin-finned structures are developed using separately manufactured fin and base components. Fin thickness, spacing, and joint design are determined based on heat load, airflow, and manufacturing requirements.

Explore our manufacturing capabilities ↗

From profile to ready-to-assemble part.

Let's evaluate width and length, mounting surface machining, drilling and tapping, surface treatment, and packaging requirements within a single technical proposal.

Inverters

Integrated set options for power module placement, base contact surface, and airflow. Please share the module drawing and power loss.

UPS systems

Let's evaluate continuous operating conditions, ambient temperature, and fan configuration together. Please provide the available volume and duty cycle.

Motor drives

Machined heatsink options for mounting points, chassis placement, and service requirements. We can start with your mechanical drawing.

Applications serve as starting points for selection. Product suitability is determined by operating conditions and prototype validation.

What you already know is sufficient for a quote.

I have my dimensions

Please share the product code, width × length, quantity, and your machining drawing. Applicable dimensions will be finalized through technical evaluation.
