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.
Conformal cooling of injection molds shortens and accelerates the production process.
We make the conformal cooled molds day by day on the highest quality 3D printers. Using of conformal cooled molds does not require additional investments.
Improving the quality of moldings
Thanks to the evenly cooling of the entire volume of the molds, the end products are of the highest quality.
Production efficiency increase
Better cooling shortens the production process and allows to significantly increase the efficiency of injection molding machines.

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).

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
Optimization of the stamp structure and molding geometry to ensure the assumed cooling effects.
Improving the parameters of the injection process without the need for many physical tests.
DURABILITY OF CONFORMAL COOLING MOLDS
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
How to order a conformal cooled mold?
- Defining the problem and setting assumptions, for example: long cooling time, deformations, surface defects
- Preparation of the necessary data
- molding model
- model and documentation of the injection mold
- information on the material of the molding
- injection process parameters
- Sending a query to: firstname.lastname@example.org
