the merit of the Gas-assisted injection molding—slight warp and distortion of products. […]
the merit of the Gas-assisted injection molding–low injection pressure and locking force
the merit of the Gas-assisted injection molding—low injection pressure and locking force, thereby reducing cost for equipment, since gas-assisted injection adopts “ underfeeding injection”, […]
a technical process of gas-assisted injection molding– Discharge of gas
Discharge of gas. When the product is cooled until it takes on certain level of rigidity and intensity,, pressure of the gas shall be discharged and recycled, finally open the cavity and eject the product.
a technical process of gas-assisted injection molding– Gas dwell
Gas dwell, upon the completion of filling in the mold cavity and on the premises that the gas pressure is preserved, the product should be put aside until it gradually cools to compensate shrinkage of the product due to the cooling of materials. […]
more informations about gas injection stage
I want to say something about Gas injection stage, this stage plays a very significant role in the whole production process in which it directly influences the final quality of a product. […]
a technical process of gas-assisted injection molding– Gas injection
Gas injection, inject high-pressure inert gas such as nitrogen into the core of fusant and the gas enveloped by plastic fusant shall move forward along a direction with minimum resistance and meanwhile push the flowing front of fusant to move further forward unitl the mold cavity is fully filled. […]
Introduction to Micro Tool Types
Another reason micro hard milling is growing in popularity these days is that micro cutters are being offered in more expansive ranges of cutter reach lengths, provide longer cutting lives and generate near perfect surface finishes. And cutters are manufactured to exacting tolerances. For example, some cutting tool manufacturers hold diameter tolerances on their micro [...]
Introduction to Micro Hard Milling Applications
Many of today’s shops involved with micro machining are doing so on extremely hard metals, such as CPM (1-V, 3-V, 9-V) D2, A2 and F7 tool steels, along with hard powdered metals, all of which can be as hard, or harder than, 62-64 Rc. They also micro machine stainless steels like 450, 410, and 17-4 [...]
How to select a right gate for your mold
The tab gate —the most commonly used of the three—consists of a trapezoidal block milled into the parting line on an exterior surface of the part and is usually placed in a thicker wall section rather than thinner areas. Its position usually makes it easy to trim off, and while it typically leaves the largest [...]
A right drilling in mold manufacturing is very important
Drilling in mold manufacturing often differs from conventional drilling with respect to several key factors. For one thing, there is a greater frequency of contoured drilling surfaces. For another, the industry employs tougher materials than are typically encountered in general machining. Successfully dealing with these conditions requires an application-specific machining strategy. […]
