Conformal cooling

Conformal Cooling

Conformal cooling is a system of cooling channels designed to follow the shape or profile of the mold core as close to the work surface as possible to perform a rapid homogeneous cooling process in injection molding or blow molding.

3D printing technology in conformal cooling

Production technology: SLM

Machine: Concept Laser M2 cusing Multilaser

Machine work space: 250x250x280 mm

Maximal product dimensions: 245x245x250 mm

Available materials:

  • Stainless steel 17-4 PH
  • Stainless steel 1.4404
  • Hot work steel 1.2709

Roughness of the finished product without additional surface treatment: Ra 5,8-11

Maximum diameter of cooling channels: 6mm (diameter over 6mm possible after using a different channel shape)

Minimum diameter of cooling channels: 3mm

Material hardness after printing: 35HRC

Material hardness after heat treatment: 35-55 HRC


SURFACE TREATMENT of 3d printing

Elements manufactured using additive manufacturing (3D printing) can be machined. Their machinability is not different from machining castings or forgings.

On the example of a hot work steel print (1.2709) a turning operation was carried out on the DMG MORI CTX ALPHA turning-mill center. The machine operator installed a cutting insert - Kennametal (VNMG 160408).

Feed: F0,2 mm/rev

AP: 1mm

Spindle rotation: 2300mm

Cooling channels cleaning

The products offered by RCIT may seem much more difficult to clean, in the case of cooling channels obstruction. For this purpose, you can use a special device for cleaning cooling channels created in the conventional and additive method. Its design allows impulse pumping of the cleaning medium using both high pressure and appropriate temperature.

Simulation of the injection process with conformal cooling


Thanks to our own research, prototyping of fully functional models with early technology users and the support of the Foundry Institute, the tools manufactured by us should withstand a comparable number of injection cycles with a shorter duration.

If the tool is worn out earlier due to construction or design defects, the purchaser has the right to compensation. Types of compensation:

  • replacement with a tool without a defect
  • reimbursement for a damaged item


Case study

How to order a conformal cooled mold?

  1. Defining the problem and setting assumptions, for example: long cooling time, deformations, surface defects
  2. Preparation of the necessary data
    • molding model
    • model and documentation of the injection mold
    • information on the material of the molding
    • injection process parameters 
  3. Sending a query to:

Based on the above information, Infinitech3D will prepare a free analysis in the Moldex3D simulator and initial price offer.
