Introduction to mold temperature machine
Mold temperature control machine, also known as mold temperature control machine, was originally applied in the temperature control industry of injection molds. Later, with the development and application of the mechanical industry, mold temperature machines are generally divided into water temperature machines and oil temperature machines, and the controlled temperature can reach ± 0.1 ℃.
Mold temperature machines are widely used in various industries such as plastic molding, die-casting of light guide plates, rubber tires, rollers, chemical reaction vessels, adhesives, and mixing. In a broad sense, it is called a temperature control device, which includes temperature control in both heating and freezing aspects.

method of calculation
A、 Calculate the power of the heater or freezer KW=W × △ t × C × S/860 × T
W=weight of mold or cooling water KG
△ t=the temperature difference between the required temperature and the starting temperature.
C=specific heat oil (0.5), steel (0.11), water (1), plastic (0.45~0.55)
T=time to heat up to the desired temperature (hours)
B、 Request the size of the pump
Need to understand the pump flow rate and pressure (head) required by the customer
P (pressure Kg/cm2)=0.1 × H (head M) × α (specific gravity of heat transfer medium, water=1, oil=0.7-0.9)
L (media required flow rate L/min)=Q (mold required heat Kcal/H)/C (media to hot water ratio=1 oil=0.45) × △ t (temperature difference between circulating media entering and leaving the mold) × α × 60
2. Selection of freezer capacity
A. Q (freezing capacity Kcal/H)=Q1+Q2
Q1 (Heat brought into the mold by raw materials Kcal/H)=W (Weight of raw materials injected into the mold per hour KG) × C × (T1-T2) × S (Safety factor 1.5~2) T1 Temperature of raw materials in the material tube; The temperature at which T2 finished products are taken out of the mold; The heat generated by Q2 hot runner is Kcal/H
B、 Quick calculation method (not applicable with hot runner)
1RT=7~8 OZ 1OZ=28.3g (including safety factor)
1RT=3024Kcal/H=12000BTU/H=3.751KW
1KW=860 Kcal/H 1 Kcal=3.97BTU
