please don't limite your design when you design a plastic part, because it Increases your design options and requirements and still keep costs down, and plastic is easy in producing complex shapes. you know, when we design a metal product, there are many many design limitations if we put several metal stampings or castings fastened [...]
Mold validation stages Does the mold work? Activities during this phase relate to the validation of the injection mold’s mechanics. The mold is mounted into the press and dry-cycled (no resin is injected) to ensure it opens and closes normally at operational temperature. […]
the material additive processes lead fastest to moldings and are therefore the most promising. These also include new and further in RP. Examples of such techniques are laser sintering, […]
Time and cost are becoming more and more important factors in the development of new products. It is therefore extremely important for the injection molding industry to produce prototypes that can go into production as quickly as possible. […]
Polishing is essentially the removal of metal by the action of free abrasive grains carried to the work piece by a tool. The difference between these methods is only the degree of removal. […]
The aggregation of stryrene monomer,acrylonitrile monomer and butadiene rubber can produce a polymer (ABS) constituted by acrylonitrile ( A ), butadiene rubber ( B ) and styrene ( S ) in various proportions. The characteristic thereof, due to the ingenious combination by the three components, shows such features as high impact resistance, large tensile strength [...]
In the injection molding world, everybody has an opinion about how molds should be gated – how many should be used; where should they be located; and, what size and shape should they be? Much of what is actually implemented into mold designs comes from experience, whether it is from the moldmaker, molder or material [...]
“How can we mold more parts on the same equipment in less time and lower our costs?” is a standard question whose common answers include reduce cycle time and/or improve mold yield efficiency. Surface treatments have been part of this solution and in the last 10 years a new family of coatings—DLC (diamond like carbon)—has [...]
here is a mold with transfer or insert technique, it also can mold two-colored materials or two different materials in one mold, […]
