What are stack Molds?
Stack molds are some of the most interesting manufacturing tools to be found anywhere in china and around the world . The engineering skills that goes into the design if a stack mold is truly a piece of craftsmanship for a custom injection molder maker like our company!
What is a stack mold?
Stack molds are molds with a (even) series of the same cavity's and cores to produce the same parts in ONE mold. This with the purpose to increase the output of the mold ( and injection machine) to
For the layman, who has never built a plastic injection mold, it might look like a huge , fancy piece of machinery that produces plastic parts. Yet, from the perspective of an plastics mold maker, stack molds represent a very high level of expertise.
What variations do we know of stack molding?
There are numerous variations on the theme of stack molds, but some common features are:
Basically, a stack mold has a stationary "A" half, and at least two "B", or move able halves. They are similar to the rotary molds that have been in use for many years, but are vertical rather than horizontal.
This means that the move-able cores rotate about a vertical axis, rather than a horizontal. Also, the stack mold is very compact and has a much smaller footprint.
Are stack molds expensive?
Yes, stack molds are quite expensive. That is why a high volume is required to justify their expense. However, especially in medical or cosmetic molding, the ROI is quickly realized.
Considering the tremendous amount of engineering and mold making involved, the expense is understandable. Designing and building a stack mold is not for beginners, or mold makers who cut corners! Plastic injection molding is not easy, and stack molding is on an entirely new level.
What are the applications for stack molds?
Because they are for high production products, the common applications are for cosmetics and consumables, such as deodorant or toothpaste containers. Automotive and medical products are also frequently produced using stack molds.
More and more products are being designed to use soft over-molding, such as toothbrushes or hairbrushes. These are perfect applications for stack molding.Because the part is injection molded, ovemolded, cooled and ejected in sequential cycles, production costs can be minimized.
What are the benefits of stack molding?
Stack molds are available in numerous configurations to meet a variety of molding demands. Stack molding offers an economical and efficient manufacturing solution for the production of multiple plastic parts. Injection molding companies are always looking for more efficient way of molding, and for the right
A few of the benefits of this kind of high quantity mold making process include: Increased output efficiency (productivity)

injection molded plastics parts for furniture
Our company made several injection molded parts , in small series or large series. Some components have found there way in furniture or outdoor sports applications.
These parts are normally made in PP ( polypropyleen) ABS or PP,.
As some furniture parts are used in the outdoor sometimes UV stabilizers are required . So the material utilized must be imperiousness to compelling climate, more often than not we utilize against UV material to full fill this necessity.
