Die casting is a topic of public attention, and Ctif has done a number of studies on the subject. One of them allows for deeper exploration of the multiplication pressure, allowing the metal to be compacted after the imprint has been filled, as well as thin and big sections of metal (concave convex,...). Many aspects impact the effectiveness of this compression step. Today, we are going to look at the pros and cons of zinc casting.
ctif's procedures
The test piece mold (400 x 100 mm x 3.5 mm) is fitted with kisler cavity pressure sensor, which can record the pressure transfer in the component every 65 mm. A test plan was carried out, the pressure curve was recorded, the machine injection curve (Buhler 630 tons) was recorded, and the porosity of various portions (thin regions and blocks) near to or away from the attack was studied (by double weighing technique) (by double weighing method).
Parameters that are crucial
It is the design and manufacturing characteristics of components that have the greatest influence on part quality (or molds).
Parameters for production:
Zinc casting alloys of the present day are robust, long-lasting, and cost-effective materials for engineering. Their mechanical qualities are equivalent to and frequently surpass those of cast aluminum, magnesium, bronze, plastics and most cast iron. Zinc alloys were a go-to material in the 1990s because of these features, as well as its superior finishing abilities and flexibility in terms of casting process:
Reduced assembling operations.
The full assembly may be cast as a unit without costly human assembling process.
Decreased production of finished goods.
The full assembly may be cast as a unit without costly human assembling process.
Less adaptable materials are needed
The superior casting fluidity, strength and rigidity of zinc allow the thin-wall design to cut weight and save material expense.
Reduce machining operations
Because zinc alloy has high net form casting capabilities, machining may be avoided or considerably reduced.
Improved efficiency and extended product lifecycles
Much more quickly made die cast zinc than aluminum or magnesium Tools and equipment have a much longer lifespan and cost less to operate because of this.
Eliminate bearing and ring
The superior bearing and wear resistance of zinc offer more design freedom and minimize secondary production costs by removing tiny bushings and wear-resistant components.
Low, medium and high output selection
A variety of casting technologies may be employed to affordably create any size and quantity necessary.

Parameters that are crucial
It is the design and manufacturing characteristics of components that have the greatest influence on part quality (or molds).
Parameters for production:
- An increased degree of double pressure (1000 bar is more favorable than 600 bar)
- Delay before applying pressure (a short delay of 100 ms is more favorable than a normal considerable delay of 400 ms) (a low delay of 100 ms is more advantageous than a typical significant delay of 400 ms). The tolerated delay is proportional to the thickness of the assault, but also to the thickness of the component
- The compression pressure level compresses the pore type flaws, but does not eradicate them. As evidenced in the following hot foaming test (which makes them resurface), the lower metal injection temperature (660 ° C) is more beneficial than the higher temperature (700 ° C)
- A greater particle thickness (50 mm to 15 mm) is more favorable since it may slow down the solidification of the attack region of the component and shift the trigger point of the fast injection phase (less entrained air) (less entrained air)
- Thickness of the casting. Smaller attack thickness (1 mm) will lead to quick solidification and avoid the transfer of doubled pressure, while bigger thickness is plainly beneficial to the quality of components.
- The porosity achieved with alsi9cu3 (FE) is lower than that obtained with alsi12, whether in large or fine areas
- The transfer of pressure (and the quality level reached) will be diminished when a person is removed from the casting assault.
- Combined bubbling flaws (trapped air) and shrinkage defects reduce sound significantly in large regions (20 mm) compared to narrow portions (3 mm) (volume shrinkage during solidification)
- The same level of health in huge regions as in small does not result from doubling the pressure.
