Thermal contact resistance in injection molding

Polymer Engineering & Science, 1990
AbstractThis paper describes a method for obtaining the thermal contact resistance (TCR) between an injection molded part and its mold. Due to the absence of TCR the simulated cooling times obtained from Polycool II, a computer aided engineering (CAE) package for cooling simulation of injection molding, have compared poorly with both field and ...

Experimental techniques for thermal contact resistance measurements

Experimental Thermal and Fluid Science, 1993
ABSTRACT A number of different experimental techniques have been used to determine the thermal resistance of materials in contact, depending upon specific test requirements. These techniques and associated experimental facilities are reviewed, including the traditional cut-bar vertical-column test facilities, and more specialized facilities and ...

Minimizing the Thermal Resistance of Pressed Contacts

Journal of Mechanical Engineering Science, 1982
A procedure is described for predicting the recommended insert thickness which will result in minimizing the thermal resistance of a pressed contact between fiat, non-wavy, surfaces. The analysis is based upon the assumption of ideal plastic asperity deformations occurring at the interfaces formed between randomly high rough surfaces and the insert ...

Instrumentation to measure thermal contact resistance

Measurement Science and Technology, 2003
Instrumentation was developed to measure the thermal contact resistance across metallic contacts by varying the contact pressure in different environments. Experiments were conducted on oxygen free, high conductivity (OFHC) copper cylindrical flat contacts and the measured thermal contact resistance is in good agreement with the theoretical models ...

Hardness of steel and thermal contact resistance

Journal of Materials Science, 1982
Experiments on steel samples are reported for a new type of hardness tester based on the measurement of thermal contact resistance. These experiments have been carried out using a machine-mounted probe and a newer hand-held double-probe. It is shown that, by using the double-probe, errors due to the sample not having reached ambient temperature can be ...

Thermal-Contact Resistance in Finned Tubing

Journal of Heat Transfer, 1960
Interference-fit finned tubes depend for their heat-transfer capability upon a contact pressure between fin and tube. The bond resistance under such conditions is relatively small compared to the other resistances in the heat-flow path. At elevated temperatures, however, differential thermal expansion between fins and tubes completely relaxes the ...

Contact Thermal Resistance in Management of Thermal Modes

2006
Three models of contact thermal resistance for managerial processes by thermal conditions of metallurgical manufacture are submitted. The first model is submitted by a system of the parabolic equations. The second model is featured by the system of the hyperbolic equations including a relaxation time, and is characteristic for high-intensity, impulse ...

Modeling Thermal Contact Resistance

1995
One difficulty in using cryocoolers is making good thermal contact between the cooler and the instrument being cooled. The connection is often made through a bolted joint. The temperature drop associated with this joint has been the subject of many experimental and theoretical studies. The low temperature behavior of dry joints has shown some anomalous
