Stack molds are some of the most
amazing production tools that are found anywhere. The craftsmanship that goes
into a stack mold is truly a marvel.
It might look like a big, fancy
piece of machinery that produces plastic widgets for the layman, who has never,
took part in making plastic mold. Yet, stack molds represent a
very high level of expertise if you observe from the perspective of a plastics
mold maker.
Know About stack mold
On the theme of stack molds,
there are numerous variations, but some common features are:
Built for very high production
runs
To injection mold,
multi-materials Use index able cores
In the molding cycle, it can do
multiple operations
Have and multiple cores and a one
cavity
Whether stack molds are expensive
or not?
Yes, stack molds are indeed quite
expensive. That is why to justify their expense a high volume is required.
However, the ROI is quickly realized especially in medical or plastic
mold making.
Applications for stack molds
The common applications are for
cosmetics and consumables, such as deodorant or toothpaste containers as they
are for high production products. Using stack molds automotive and medical
products are also frequently produced.
To use soft overmolding, more and
more products are being designed such as toothbrushes or hairbrushes. For stack
molding, these are perfect applications.
Benefits of stack molding
To meet a variety of molding
demands stack molds are available in numerous configurations. For the production
of multiple plastic parts, stack molding offers an economical and efficient
manufacturing solution. Injection molding companies always look for a more efficient way of molding like a plastic mold maker.
- Increase in output efficiency (productivity)
- Without increasing, press size or clamp tonnage
produce twice as many parts, which greatly reduces part costs
- There is a division in set-up time and run-time
costs by all the parts produced
- Decreases number of machines required
- For stack molding producing the front and back
parts of a key fob at the same time is a good example of an application
