Applications and Benefits
Based on the above characteristics, in the following applications can be considered within the scope of use of high thermal conductivity of copper alloys:
<1> injection mould core and cavity-type, Core plugs and cooling plate;
<2> composite plastic profile extrusion die used in the process: here the use of high thermal conductivity copper alloy mould can make to improve the thermal conduction velocity, but also can improve part of the dimensional stability;
<3> production of liquid packaging bottle blow mould;
<4> Injection nozzles: the use of high thermal conductivity copper alloy, due to the thermal conduction time is short, to maintain a uniform temperature can greatly simplify the entire temperature control system, thereby reducing energy costs.
In the injection mould can consider the application of copper alloys are mainly the following reasons:
<5> in the application of a high thermal conductivity copper alloy, the mould cooling rate has greatly improved the production cycle can be shortened at least 20% (according to some users said the production cycle can be shortened or even 80%);
<6> As production cycles shorten working hours, so each class produced a significant increase in the number of parts, productivity can increase at least 25%, according to auto headlights industry some users say that their productivity and even increased by 500%;
<7> As the cooling rate increased, the mould temperature decreases rapidly, forming part of the time, so die in the “hot spots” caused by the amount and extent of the damage can be reduced, thus greatly improved the quality of parts, significantly reduced the rate of deformation of scrap ;
<8> scrap rate reduction also indicates that a part of each after each injection moulding quality is more stable;
<9> due to the high thermal conductivity copper alloy with a super heat conduction properties (in general, its thermal conductivity than steel, high-five to 10 times), die in the heat sensitive areas can be quickly disseminated to go out, so direct contact with part of the mould and parts the complexity of the cooling can reduce the number of channels or directly to eliminate;
<10> As the mould cooling channels to reduce the number of mould processing costs can be greatly reduced cost – and cooling the tool steel die slow compared to the manufacturing cost can be reduced four times.
The above examples illustrate, using the high thermal conductivity copper alloy cores later to save time and costs arising from its benefits.
Bumper in the automotive manufacturing process, aluminum bronze inserts can be applied to the steel into moulds, and some manufacturers even use the full range of high thermal conductivity copper alloy cores and cavities to produce their bumper.
Car dashboard can also be used include aluminum bronze inserts in the mould production, and production of steel used in plug-ins compared to the thermal conductivity was increased by 3 times.
To make today’s mould shop can maintain a competitive capacity to enable the world to compete with low-cost production areas, the user may consider the use of injection mould production rate of high thermal conductivity copper alloy, this aspect is very important thought , because the high thermal conductivity copper alloy mould processing plant can have higher productivity, both to save money, but also improve product quality.From Website
