The advantages for Hot Runner Mold

 The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today.

Shorten cycle
The molding cycle is shortened. Because there is no restriction on the cooling time of the sprue system, the parts can be ejected in time after curing. Many thin-walled parts produced with hot runner molds have a molding cycle of less than 5 seconds.


Save material
In the pure hot runner mold, there is no cold runner, so there is no production material. This is especially significant for applications where plastics are expensive. In fact, the major hot runner manufacturers in the world have experienced rapid development in the world when oil and plastic materials are expensive. Because hot runner technology is an effective way to reduce material costs.


Reduce waste
Reduce waste and improve product quality. During the hot runner mold forming process, the plastic melt temperature is accurately controlled in the runner system. Plastics can flow into the cavities in a more uniform state, resulting in consistent quality parts. The hot runner molding parts have good gate quality, low residual stress after demolding, and small deformation of parts. Therefore, many high quality products on the market are produced by hot runner molds. 
Production automation

Production automation
Eliminating subsequent processes is conducive to production automation. There is no need to trim the gate and recycle the processed cold runner. It's conducive to production automation. Many foreign manufacturers have combined hot runners with automation to significantly increase production efficiency. Many advanced plastic molding processes have been developed based on hot runner technology.

What's the properties of POM?

  Polyformaldehyde (POM) thermoplastic crystalline polymer. Known as "Super Steel" or "Sai Steel", The English abbreviation is POM. Generally, polymers obtained by formaldehyde polymerization have a low degree of polymerization and are easily thermally depolymerized. It can be used as a raw material for organic chemicals and synthetic resins, and as a fumigant for drugs. 1.General property POM  is a hard, dense material with a smooth surface and gloss, light yellow or white, thin-walled partly translucent. Combustion characteristics are easy to burn, and continue to burn after leaving the ignition source. The flame is yellow at the upper end and blue at the lower end. Melting dripping occurs and has a strong pungent formaldehyde smell and fishy smell. POM is white powder, usually opaque, good coloring, specific gravity 1.41-1.43 g/cm3, molding shrinkage 1.2-3.0%, molding temperature 170-200℃, drying conditions 80-90℃ for 2 hours. POM's long-term heat resistance ...

There are several coloring methods for stainless steel parts

  There are several coloring methods for   st ainless steel parts 1. Electroplating Electroplating: The process of attaching a metal film to the surface of metal or other materials by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, reflectivity and enhance aesthetics.   2. Water plating It does not rely on external power supply in the aqueous solution, but only relies on the reducing agent in the plating solution to carry out the chemical reduction reaction, so that the metal ions are continuously reduced on the autocatalytic surface to form a metal plating layer.   3. Fluorocarbon paint Refers to coatings with fluororesin as the main film-forming substance, also known as fluorocarbon paint, fluorocoating, and fluororesin coating.   4. Spray paint The paint is sprayed into a mist with compressed air and applied to the stainless steel plate to form different colors.   Additional ： The current color stainless steel pl...

What is 'Catch hook and thin-wall' of plastic mold products?

What is 'Catch hook and thin-wall' of  plastic mold products ?​ 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe.  Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.
