Injection speed is too fast, gate/sprue/runner size is too small, or the melt/mold temp is too low. Jetting: Jetting is a snake-like stream which occurs when polymer melt is pushed at a high velocity through restrictive areas. Poor tool design, gate position or runner. Injection speed set too high.
After the plastic has cooled, the mold is opened and the part is ejected. [2] "Straight extrusion blow molding is a way of propelling material forward similar to injection molding whereby an Archimedean screw turns, feeding plastic material down a heated tube. Once the plastic is melted the screw stops rotating and linearly moves to push the ...
In gas-assisted molding, the plastic material is injected into the mold cavities like the regular injection molding process but only up to 70%~80% of the mold volume. The melted plastic in contact with the mold walls begins to solidify, then nitrogen gas is injected into the mold through strategically designed and placed gas inlets, providing ...
Multi-material injection molding (MMM) is the process of molding two or more different materials into one plastic part at one time. [1] As is the case in traditional injection molding, multi material injection molding uses materials that are at or near their melting point so that the semi-liquidous material can fill voids and cavities within a pre-machined mold, thus taking on the desired ...
A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...
The concept of the Thingmaker was introduced in 1963, as part of Mattel's Vac-U-Maker set. This omnibus toy combined the new moulds and Plasti-Goop technology with the existing Vac-U-Form machine, a vacuum forming toy, which molded simple sculptures by heating thin sheets of plastic, then using a vacuum pump to form the softened plastic over hard plastic forms.
Price on Etsy: $1,650 While most blow molds are 100% plastic, this Santa face from the ’50s embedded in a wood frame is the only plastic piece classifying this decoration as a blow mold.
An all-electric injection unit with 14 mm screw to inject the polymer melt into the mold; Arburg developed a micro injection molding machine with an 8 mm injection to ensure high degree of dosing precision. This type of machine is combined with a second screw, which is responsible for melting and homogenous mixing of the material. [2]
