At DSW we have now various tooling options available to you, offering different quantities of capability from prototype to short pre-production runs to full production quantities.
Construction Injection Molds Classification
classification or types of mold injection very depend on what we should make the plastic parts, because every parts have specific and different design. when design molds we should see precisely what the influencing factor like geometry, quantity of cavities, ejection principle, plastic material and form of parts.
The essential classification of mold according to construction shown on picture below
1. Standard Molds
the regular mold is easily the most simple design, basically the standard molds is identical to two plate molds construction, they divided in 2 side : cavity side and core side, cavity side is the side that construct to flowing plastic material from nozzle to cavity parts, basically they contain sprue, runner.
Plastic Mold,2 plate moldcore side construct to create shape for core, demolding system and ejection system, at the side we design ejection system.
standard mold have one parting line, and also have one opening direction. this sort of mold utilize in all kinds of plastic parts that doesn’t have undercut, inner and outer screw.
Light brown color little and straight in ejection product is shown ejector pin.
2. Slide mold
development with this mold type may be the used slider parts in several molds types, plastic mold maker is transfer horizontal movement of mold to vertical movement, this varieties of molds is commonly used to produce parts with undercut, you must see more at the post once we need slider for get more information.

basically three plate molds has two parting line, and floating plate, floating plate support by support pin, Ever since the mold has two parting planes, the runner system might be found on one side of floating plate or make special plate that attach in floating plate, we called runner plate, see post about runner plate.Three plate molds are 71dexlpky because of their flexibility in gating location. this kinds of molds is flexible make use of in multiple cavity.
Plastic Mold,3 platesnote : floating plate also referred to as cavity plate or plate number 3, to know more the many between two plate mold and three plate mold start to see the posting about Simple and easy Types Molds Construction
4. Split Cavity Mold
simply the split cavity is same as 2 plate standard mold, nevertheless the cavity have split block to produce undercut product or external threads.
Plastic Mold,Split Cavitythis sort of mold use as soon as the slider will not be enough to produce the undercut or the threads. the disadvantages of this mold happens when use for little parts, the development will difficult.
5. Mold With Screw Device
this mold special to produce thread forming, the core could be rotate when demolding process, both internal or external threads may be forming from this type mold.
After plastic design elements and expense elements have already been considered, it’s time to get the plastic molded. This method is done entirely on the part of production team. In fact,DSW is not really a consulting or design firm, but in addition a trouble shooter and analyses technician. The steps in the molded plastics production process are well planned and stick to industry certification standards. Furthermore, customers get the main benefit of experienced plastics engineers taking care of their component part. The plastic is cooled and packaged after molding.
