multi-cavities mold design
Using a mold with fewer cavities (less than 8 cavities), its production capacity is far from meeting its demand. If multiple sets of molds and multiple injection molding machines are used to produce at the same time, the cost is very high.In order to meet the large demand for products and reduce production costs, multi-cavities molds have become a solution to the above problems.Using a multi-cavity mold can greatly improve production efficiency and reduce production costs through a set of molds and an injection molding machine, thereby improving the market competitiveness of products.
Design points of multi-cavities molds
Mold layout design
1.The number of cavities of multi-cavity molds is generally: 8CAV, 12CAV, 16CAV, 24CAV, 32CAV, 48CAV, 64CAV, 96CAV, 128CAV, etc.
2.Make a separate insert for each cavity to prevent machining errors and control precision
3.The cavity and core inserts can be designed to be higher than the parting surface of the AB plate to improve the accuracy and reduce the processing cost of the mold base.
4.Each individual cavity insert needs to be marked to avoid assembly errors.
Feed system design
1.Runner and gate balance is a key consideration and problem in design.
2.Design inserts at the position of the gate as much as possible to control the dimensional accuracy for the convenience of processing.
3.MoldMaster, Husky, INCOE, MANNER, Synventive, DME, Hasco, are the hot runner brands we often use for multi-cavity molds,It is designed in the form of hot half mold, which is convenient for assembly, disassembly and maintenance.
4.Fill imbalances are often addressed with Melt Rotation Technology.
Cooling system design
The length of the fill period, a large factor is determined by the Cooling system.
The hot runner system must be designed separately for the cooling circuit.
All mould bases are individually designed to Cooling.
