Hot chamber die casting means that the pressure chamber is immersed in the liquid metal in the heat preservation melting crucible, and the part is not directly connected to the engine base, but is installed on the crucible. It is suitable for die-casting zinc and other non-ferrous alloy parts with low melting points, and can be widely used in industrial sectors such as automobiles, motorcycle parts, instruments, household hardware, and household appliances.

Hot Chamber Die Casting Capability
Compared with cold chamber die casting, its injection pressure is much smaller, generally around 7 to 14 MPa, so hot chamber die casting machine generally does not have a pressurized hydraulic cylinder. Due to the long-term sinking of pressure chamber components in molten metal, hot chamber die casting is mostly used for die-casting zinc alloy and other low melting point alloy castings. Since no additional pouring operation is required, the hot chamber die casting machine saves cycle time and has higher production efficiency than the cold chamber die casting machine. We provide the whole hot chamber die casting process (from die design to transportation).
Advantages of Hot Chamber Die Casting
Hot chamber die casting is suitable for die casting of low melting point alloys such as zinc alloy. Compared with cold chamber die casting, it has many advantages: easy to realize production automation, high labor productivity, less metal consumption, stable process parameters, better quality of die castings, and improved working conditions.
Advantages of Hot Chamber Die Casting
Hot Chamber Die Casting Alloy
Hot chamber die casting has molten liquid and semi-liquid metal in the metal pool, which fills the mold under pressure. At the beginning of the cycle, the piston of the machine is contracted. Pneumatic or hydraulic pistons squeeze the metal and fill it into the mold. Generally speaking, the hot chamber die casting process is used for alloys of zinc and other alloys.
Quality Control Of Hot Chamber Die Casting
In the hot chamber die-casting production process, selecting the appropriate process parameters is a prerequisite for obtaining high-quality castings and exerting the maximum productivity of the die-casting machine, and is the basis for the correct design of the die-casting mold.
During die-casting, there are many factors that affect the filling and forming of the alloy liquid, mainly including injection pressure, injection speed, filling time, and die casting mold temperature. Due to the low heat capacity of the zinc alloy, the injection system of the hot chamber die casting is required to provide sufficient energy to meet the requirements of fast filling.

Zamora (Zamora Chinchipe).- Este Lunes en las instalaciones del auditorio del Distrito de Salud 19D01 Yacuambi – Zamora, la Coordinación Zonal 7 del Ministerio del Deporte, realizó el casting de instructores y coordinadores para la quinta edición del proyecto emblemático Ecuador Ejercítate 2017.
Instructores de los diferentes cantones de la provincia de Zamora Chinchipe asistieron al llamado, demostrando sus habilidades al ritmo de la bailo terapia y aeróbicos.
“El objetivo de Ecuador Ejercítate en esta su quinta edición es seguir promoviendo la práctica de actividad física, además de hábitos saludables para superar los problemas derivados del sedentarismo, malnutrición y mal uso del tiempo libre” destacó Diana González Coordinadora Zonal 7 de esta Cartera de Estado.
Por su parte, Erika Guayllas participante del casting manifestó “Esta es una oportunidad de trabajo para nosotros los jóvenes, además estamos realizando lo que nos gusta y estamos permitiendo que otras personas se beneficien del deporte como un elemento importante para la salud”.
En la actualidad el proyecto Ecuador Ejercítate cuenta con 202 instructores, pero se tiene planificado para este año poder contar con 248 instructores en todo el país.
Por otra parte González recalco que dentro de los requisitos para la elección de los instructores se ha tomado en cuenta que dentro de sus perfiles sean especialistas en bailoterapia. JC/Ministerio del Deporte
Dato: Los resultados se podrán saber el miércoles en las oficinas de la Coordinación Zonal 7 del Ministerio del Deporte de 10h00 a 17h00.’
First try, second try and original.
The second try I did hotter and it seems to have recorded more detail from the mould.
This could become addictive. Next step order some lead free pewter.

Materials. Any resin available in liquid form can be cast. Castable resins include phenolics, polyesters, epoxies, silicones and acrylics.
Types of molds. The type of mold used depends on the plastic, the size and shape of the part, and other design considerations.
Draw mold一No undercut is possible. Flutes and scallops must run in the direction of removal. Taper must be provided to break the vacuum and reduce friction. Castings are removed by force, and minimum wall thickness is critical, running from 1/8 in. on tiny parts to 3/16 in. on parts the size of radio cabinets.
Split mold~Undercuts may be provided if they do not prevent release from the separate parts of the mold. Minimum wall thickness is 3/16 in., and parts less than 0.1 lb are not commonly produced economically.
Cored mold~This type allows complexity of design, but is not usually feasible from a cost standpoint for parts less than 4 x 4 x 4 in. Molds require no taper. Minimum wall thickness is 3/16 in. Mold shrinkage allowance must be considered. Extremely large parts may be cast.
Flexible mold一Model may be constructed of wood, porcelain, metal, etc. Mold is of plaster with a lining of rubber latex or an elastomeric plastic. Epoxy materials may be cast in flexible molds, but most polyesters react with the lining material. Although parts cast in rubber molds cannot be held to the tolerances possible with matched metal molds, a reasonable degree of accuracy is reproducible.
This month's installment of In The Loop featured a bronze pour with Don Myhre, MCAD faculty member and director of the 3-D Shop. Participants got to create their own molds and witness the pour in the College's foundry.
IN THE LOOP offers a behind-the-scenes look at the art and design process at MCAD. Featuring presentations by faculty members in the College's premiere studio facilities, these intimate events include wine, hors d'oeuvres, hands-on participation, and stimulating conversation.
