Type of Injection Mold

• 

  Two Plate Mold

  Two plate mold is only two halves(moved and fixed half),the mold is good for many types of gating, and product and runner system can inject at the same time
• 

  Three Plate Mold

  Three Plate Mold add a runner plate in fixed half, Product and runner system are in the different time to inject. It is only for pin-pointing gating

Six main Systems of Plastic Injection Mold

• 

  Running System :

  The Flow Running before plastic enters the mold from the nozzle, including Sprue，Main runner,  Branch runner,Slag Well,Gate.

   

   

   

   

   

   

• 

  Form System:

  The system refers to various combinations of parts that form the shape of a product, including moved mold (Core side) and fixed mold (Cavity side). The moved mold forms the inner surface of the product, the fixed forms the outer surface shape of the product.According to process and manufacturing requirements, Sometimes, the core and cavity inserts are composed of severial assembly parts,  Sometimes inserts that made into a whole that are easily damaged and difficlut to machine.

• 
  • Cooling System:
  •  Cooling system is required to meet the temperature requirements of the injection process for the mold, and it is necessary to have a cooling system to adjust the temperature of the mold.  The common method of mold cooling is to set up a cooling water channel inside the mold, which uses the circulating cooling water to carry away the heat of the mold; The heating of the mold can not only utilize cooling water to pass through hot water or oil, but also install electric heating elements inside and around the mold
• 

  Exhaust System:

  Exhaust system is set up to exhaust the air in the injection molding process and the gas generated by the melting of plastic into the mold. When the exhaust in not smooth, the surface of the product will form air marks,charring and other defects. The exhaust system of plastic mold is usually a slot shaped air outlet that set up in the mold to exhaust the air in the original mold and the gas brought in by the molten material.

• 

  Guidance System:

  Guidance System is established to ensure accurate alignment between the moved and fixed half during mold closing,four sets of guide pin and guide bush are usually used to form the guiding components. Sometimes, it is necessary to set up mutually matched inner and outer conical surfaces on the moved and fixed half to assist in position.

   

• 

  Ejection System:

  After the product is formed and cooled in the mold, when mold is opened, the ejection mechanism (ejection pin) is pushed by the ejector pin of the injection machine, then the product and runner system is pushed from the core side, in order to proceed with the next molding cycle.

  Ejection System generally consists of several parts: Ejection Pin, Ejection Sleeve,Ejection Plate,Ejection Guide Pin and Return Springs

 Main Types of Injection Mold From Wiesel

Singel Mold: Only one cavity for part, it is good for small order	Family Mold: Many parts are in one  mold, it is good for many similar parts of small order	Overmold: the mold is good for different color and material in part.	Insert Mold: Mold is for plastic with metal, normally, the material of metal is steel, brass,etc.

What's factors affect the mold cost

Moldlife is the main factor, Because if moldlife is high, the material of mold and the way of machining is different.
