More uniform heat distribution
DME mold parts manufacturer has introduced a new D-Max series single hot sprue bush , gate set in the nozzle body with a DME standard plug-in cast- heater , compared with the traditional square coil heaters, heat more evenly distributed in the NPE 2012 show will see the products on display .
Novel D-Max is particularly suitable for series production and small samples , the use of bushings in a standardized , so mold manufacturers use the same basic components can accurately simulate multiple nozzle system - it does not require special heater nozzle tip slightly , limit or needle.
Cast-in heater plug- molded products manufacturers can better control the heating of the nozzle body , thus shortening the wiring. And when the nozzle body for life than a square coil heater about 50% longer .
D-Max gate sets have two heating zones : in the nozzle body of the plug-in cast-in heater and nozzle head square coil heater. Square coil heater using a separate thermocouple , can provide accurate temperature readings, eliminating the need for soaking process normally required .
Users can be individually controlled heaters can also be used as a zone control both . As a result of the unique heating mechanism , so the gate sets for a variety of materials , including a variety of crystalline polymers. In the development phase of the sample , using the same nozzle installed in a multi- nozzle system is very important. D-Max copy of the same type of heater and the tip slightly , so the multi-nozzle system, the response is identical with the various components of a single nozzle system .
Compared with the cold runner , hot sprue bush has outstanding advantages. Since the set length of time , depending on the diameter of the gate , the gate may cause cold cycle time is very long. When using hot runner , immediately after the injection molding can open the mold , thereby significantly shortening the cycle time. Since there is no cold runner hot runner , generate less waste .
The new D-Max Series
More environmentally friendly water-based device
Conair company introduced a new TW-HT and TW-ALT series of new mold temperature control device. TW-HT apparatus using hot water temperature of the die was heated to 200 ℃. And heating oil - compared to the heat transfer medium , the water has a high specific heat capacity , better thermal conductivity, and thermal conductivity coefficient than doubled. Compared with oil, water safer and more environmentally friendly.
As TW-ALT models, mold temperature control means periodically alternately introduced into the hot water and cold water, and the mold temperature in the injection molding process prior to the injection molding machine cycle step , the top of the product before and after the lower mold temperature, cooling the molding . Temperature control means may provide a temperature up to 200 ℃ hot water, cooling water , or up to 15 ℃ . Or the critical temperature of the mold area can change the amplitude of alternating cycles 100 ℃ . In the injection molding process, this helps to shorten the cycle of temperature variation during the molding cycle time, improve product quality and surface quality , especially for the appearance of the product and the requirements of demanding optically transparent member .
