Precision Multi-Cavity Plastic Cap Mold Custom Bottle Injection Mold Manufacturing OEM ODM Injection Moulds Plastic Molds

For our mold factory, multi cavity molds are high value-added products that reflect our design capabilities, processing accuracy, and engineering experience. It is a strategic tool that helps customers gain efficiency, cost, and quality advantages in fierce market competition. If you have a need for large-scale production, we can provide you with a complete set of multi cavity mold solutions from product analysis, mold flow simulation to precision manufacturing.

Multi Cavity Mold Proudct Range

Transportation, Agricultural machinery equipment, Construction machinery, Water conservancy facilities, Space flight and aviation, Chemical machinery, Sea carriage and so on.

Key design and manufacturing considerations
As a professional manufacturer, when designing and manufacturing multi cavity molds, we will focus on:

Channel balance: Ensure that the melt can fill each cavity simultaneously, equally, and uniformly, which is the lifeline to ensure the consistency of part weight and size. We will use advanced flow analysis software for simulation optimization.

Uniform cooling: Design efficient and balanced cooling water channels to ensure consistent cooling rates for all cavities, in order to prevent part deformation and shorten cycle time.

Mold strength and accuracy: More cavities mean larger mold sizes and more complex internal structures. We must use high-quality mold steel and perform precision machining to ensure that the mold does not deform or wear out during long-term high-pressure, high-temperature cyclic production.

Exhaust and ejection: Each cavity must have a good exhaust system to avoid trapped air and be equipped with a reliable and synchronized ejection mechanism.

Production Specification

Manufacture Process

1. Review the part design,drawings and quality standard from clients.
2. Mould and Tooling design & manufacturing
3. Mould and Tooling testing & confirm the sample
4. Die casting raw castings
5. Surface treatment: Trimming,Deburring, polishing, cleaning, passivation & power coating and other requirement from Customer
6. Precision machining: CNC lathes, milling, drilling, grinding etc
7. Full Inspection
8. Packing
9. Delivery

When is it applicable?
Multi cavity molds are not omnipotent, they are most suitable for:

1. Parts with high demand and long lifecycle.
2. The part size is relatively small to accommodate multi cavity layouts.
3. Large scale production projects that are sensitive to cost control.

About Us

1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity ;
9. For the complex mould which is difficult to demould, we can manufacture the automaitc mould with take out device ;
10. We produce the pattern sample to customer after finish the mould, when the pattern was qualified, then we do exceptance job for the mould ;
11. We have the Hexagon coordinate measuring instrument imported from the Switzerland to have a test make sure our mould qualified.
