In some hot runner system there is a color change cap upon the hot tips. Hot runner color change hat is hot runner equipment but not all of the nozzles have it. Hot runner supplier takes customers’ advice to install change color hat.

But what’s the function of hot runner color change hat? This question will solved by me.

As is known to all, hot runner color change hat means a part that can help hot runner injection machine change color easier. We will add color change hat on the hot tip if customer state that hot runner system is going to produce products need optimal color change ability. Due to its function and place situation, we use corrosion-resistant alloy wear-resistant material to made hot runner color change hat. So when a hot runner manufacture company need design the hot runner system, they should know which plastic resin material used and change color or not. This two points are very important to engineers.

In many of cavity mould injection,lack of hot runner simply cannot be forming.That is hot runner is the best technology to ensure the flow balance.In many of the mould cavity injection,lack of hot runner simply cannot be forming.Hot runner is to ensure that the best technology flow balance.Because plastic in port in shear force,no matter how reasonable the geometry of the mould has balance,the products forming out of is difficult to consistent weight,especially concerned for many of the mould cavity is,if do not use hot runner,the products ouside forming out will be lighter than the inside.

To the plastic processing manufacture,as long as there is a certain batch injection production,using hot runner is economical.Because hot runner technology help enterprice deduce the waste material in injection moulding production.In most case,waste material can not used for recycle.Some times the waste material weight is equal to producets.If adop traditional injection type,it mean that the waste material is as manfg as the products.Valuing,use hot runner,can save 30% ~ 50% of raw materials.In addition,would help reduce the wear and tear of mould,extend the service life of mould.Generally speaking,hot runner service life is twice times longer than small gate mould.
 

Although the composition of hot runner is simple,but its every part plays a very important role.Usually,good quality,structural design and material requirements of hot runner are very high,that is the premise to ensure the quality of hot runner and hot runner function.

In the injection molding production, decided whether to use the hot runner system  in any situation to be more economical, usually needs considered from the technical factor and the economic agent two aspects.

1st, technical factor

From the technical angle judges whether to use the hot runner system, generally needs makes the decision together by the product development personnel and the mold manufacturer. In the judgment process, may invite the hot runner system supplier to participation discusses and provides the essential technical support. In ordinary circumstances, regarding certain large-scale, thin wall injection molding product or structure complex product, for example large-scale television's shell, automobile bumper, air conditioning face guard and so on, when uses the cold runner mold is unable to take shape or the formation very difficulty, the hot runner system usually is the first choice technological means; Some injection molding product, although uses the cold runner mold also to be able to take shape smoothly, but stems from to the product certain performance request, for example mechanical properties, superficial artistry, optics request, shape and structure stable and so on, often needs to use the hot runner system to improve the plastic the fluidity; Specially, if use pin valve type hot runner system, but may also through to the time active control, the change cementing mark distribution, even eliminates the cementing mark. 2nd, economic agent From the economical angle decided whether to use the hot runner system, usually is with the economical repayment which its brings carries on the hot runner system's purchasing expense the comparison. In the actual inspection, needs to carry on the computation contrast according to the product manufacturing special details. Aspect and so on additional profit which the supposition in one year complete production cycle, uses the hot runner system to bring the raw material saving of expense which, the energy conservation expense, the production efficiency enhancement as well as the mold scale expands produces sum totals to be bigger than purchases the hot runner system price 2 times, then the injection molding producer does not have the risk to the hot runner system's investment. In the choice and the use should pay attention question Chooses the hot runner system's key chooses the good supplier. Because the hot runner technology is a dynamic applied technology, it along with exploitation conditions' difference, has the very big variable. In the practical application, the system analysis and the application experience are frequently very important. Therefore, the supplier provides should not only be the hot runner product, more importantly, the supplier should also provide the system analysis and the thorough technical service, has contained the earlier period technical advisory work.

A qualified hot runner supplier, must have the basic condition is:

Has the specialized technical team and the service troop;

Has the legitimate general flow analysis software (for example the MoldFlow software). The hot runner supplier only then has the software supplier's technical support for a long time, can obtain the accurate analysis result. If uses pirates analyzes the software, gives the analysis report often in false, different with the general operating system software, those who analyze the software to provide is the engineering design basis and the security, but the general operating system software provides a working platform merely;

Has the precise numerical control processing equipment, makes the high accuracy the hot runner product;

Has many year rich application experiences;

Has the sufficient spare parts stock or spare parts manufacturing capacity.

Regarding the above basic condition, if lacks any link, has the possibility to cause the customer to the hot flow channel application defeat.

The injection molding producer when chooses the hot runner system, should pay attention to the following several points fully:

In the product development or the mold design stage, must express all specification fully as far as possible, and all engineering data will provide fully to the hot runner supplier, so that the supplier can obtain the enough design basis, achieves the best project objective; After the hot runner supplier provides the design paper, should unify own mold structure, scrutinizes carefully and confirmed. If acts according to the hot runner supplier's request, needs to carry on the processing to mold's certain spots, must carry on strictly according to the blueprint, otherwise, the small modification has the possibility to cause system's defeat .
