Technical Questions
What is the thermal insulation board?
It can stop the temperature from moving from one point to another point. Here we refer to the mould thermal insulation boards, like our products Keeprecision series 250-BL, in the temperature 250℃,it can bear the pressure of 350N/mm2. It is made of resins, fiberglass and others which has good mechanical strength and compressive strength.
How to select the thickness?
We have inquiry service for your questions in our website, please refer to our website.
How to improve the availability of the thermal insulation boards?
We have the advanced software of cutting and division, please refer to our technical innovation in our website.
What is steady state heat transfer and non-steady (transient) heat transfer?
Steady heat transfer means the heat transfer ways according to the position, not the time.
non-steady (transient) heat transfer means the heat transfer ways according to the position and the time.
What is cold surface temperature, hot surface temperature?
The temperature of source terminal is called hot surface temperature, the opposite terminal is called cold surface temperature, while the thermal insulation board is in the middle. They are two important factors for selecting materials and designing the thickness. Please refer to our website.
What is the coefficient of thermal conductivity?
It is a kind of capability of temperature transfer. Under the steady temperature transfer, it refers to how much energy transferring through the materials of 1mm thickness in the time of one second and in the area of one squaremeter, while the sides of the material have only 1 ℃ difference in temperature.
What is quality standard of your thermal insulation materials?
Usually we do it according to the DIN ISO2768. If you have any other special requirements, please let us know it.
What is the linear expansion coefficient?
The linear expansion coefficient of solid material temperature is changed each 1 degree Celsius, change its length and its length at O DEG C ratio, it is called the "coefficient of linear expansion". The unit is 1/ open. Symbols forα1. Its definition is a1= (lt-l0)/l0t, lt=l0 (Lalt). Because the material is different, the coefficient of linear expansion is not the same, their numerical and actual temperature and determine the length of the selected 1 reference is related to temperature, but due to the solid linear expansion coefficient changes little, it can usually be ignored, and take a as a constant independent of temperature.
Where are the thermal insulation materials installed?
Usually for moulds, they are installed in the middle of moulds and mould bases, or side face of the moulds. Or wherever you request.
What are the ways of transfer for the heat in the mould?
Usually there are three ways: heat exchange, heat radiation and convection heat transfer.
