 Transverse

 Revolution

 From the layout of the product and product size Calculate the size of the mold core preliminaries Calculate the size of the preliminary shell mold

 Choose presses must be based on the size of the mold, about open presses, about opening the

mold, the technical requirements of the product, the ability of the company

Select 2 plate mold when:

Design processing time short.

Is the little nozzle Details shorter lifespan Simple and easy to work

Select 3 plate mold when:

Products with complex shapes Product variety nozzle

Products need multiple cavity Cost more expensive molds 2 panels

Products in bulk, low cost

Products with multiple cavity must use

channel hot Products with complex shapes

Shorten delivery times

With shipments computer mouse product

number 7000 a month we will pick 3 plate

mold:

The number of orders in the average level

and the time of delivery do not fold up the

selected site will save more 3 plate mold

multiple floors

The shape is not too complex

Capable of automation compared with 2 plate mold
