01

Custom Profiles

Cross-section and tooling review against your drawing.

02

Cut to Length

Required part lengths, cut ends and deburring needs.

03

CNC Machining

Mounting faces, holes, threads, slots and pockets.

04

Surface Finishing

Anodizing and powder coating to the agreed specification.

PRODUCT EXAMPLES

Profiles and components
for your assembly.

Choose the manufacturing route around the geometry, mounting features and finish your part needs. Existing profile options and custom tooling can be reviewed during quotation.

01 / OPEN FIN PROFILES

Cut-to-Length Heat Sink Profiles

Parallel-fin extrusions can be supplied to an agreed length, with cut-end and deburring requirements identified before production.

02 / CUSTOM CROSS-SECTIONS

Integrated Fins and Profile Features

A custom section can combine cooling fins, an enclosure shape and mounting features. Feasibility depends on the complete cross-section and alloy.

Photos illustrate example geometries; tooling and availability are reviewed for each inquiry.

MANUFACTURING REQUIREMENTS

Plan every step
of your finished part.

Extrusion defines the cross-section. Cutting, machining, finishing and assembly turn that profile into a component ready for the next stage of your project.

Sharing the complete requirements early helps align tooling, process sequence and final inspection.

Material & temper

6063 and 6061 are available for review. Specify the alloy and temper required for your profile, machining and application.

Machining & dimensions

Identify holes, slots, threads, mounting faces, datums and critical tolerances on the finished-part drawing.

Finish & masking

Specify mill finish, anodizing or powder coating. Mark surfaces, bores or threads that need masking or special control.

Inspection & documentation

Agree critical dimensions, cosmetic surfaces, inspection criteria and any required material or quality documents.

Protection & delivery

Define fin protection, surface protection, packaging, order quantities and the delivery destination.

DRAWING & APPLICATION INPUTS

Make the design intent clear.

01 / GEOMETRY

Define the part

Include the cross-section, finished length, fin dimensions, base thickness and mounting features. Highlight the space available in the assembly.

02 / COOLING CONDITIONS

Share the operating context

If available, include heat load, ambient temperature, airflow, orientation and target temperatures alongside your manufacturing drawing.

03 / ACCEPTANCE

Identify what matters

Mark critical tolerances, contact surfaces, finish requirements and inspection criteria so they can be considered in the production plan.

Heat sink performance depends on the complete cooling system and operating conditions. Validate the proposed design for its intended application before production approval.

PROJECT QUESTIONS

Before you
request a quote.

These details help us review the manufacturing scope and prepare a more useful response.

Can you work from our drawing or a sample?

A dimensioned drawing is preferred. If you have a sample or an early concept, share the available information so our team can review the manufacturing requirements and identify any missing details.

Can an existing extrusion profile be used?

An existing profile may be suitable if its cross-section matches your requirements. Send the required geometry and dimensions so tooling availability can be checked. A custom die may be needed for a new shape.

Can the heat sinks be machined and anodized?

CNC machining and anodizing can be included in the manufacturing route. Identify holes, threads, slots, mounting faces, finish and masking requirements on the drawing so the process sequence can be agreed.

How are tolerances and inspection requirements agreed?

Mark the critical dimensions, datums and required tolerances on the finished-part drawing. Extrusion dimensions, cut length and CNC-machined features need their own requirements; the applicable controls are confirmed during quotation.

What affects price and minimum order quantity?

The profile, alloy, die requirements, order quantity, cutting, machining, finishing, inspection and packaging all affect the quotation. Share your expected batch size and repeat-order needs for a project-specific review.

What lead time should we plan for?

Custom die development typically takes 2–5 weeks, with the specific schedule confirmed during quotation. Extrusion, machining, finishing and delivery timing depend on the project requirements and production plan.
