Cold Chamber Die Casting Machine ADC12 Crankcase Side Cover Machine
Purpose-built for manufacturing precision-sealed aluminum alloy
crankcase side covers for motorcycle, ATV and general-purpose
engines, this 280-ton cold chamber die casting machine delivers
accurate forming of gasket mating surfaces, bolt-hole bosses and
oil-seal recesses. Crankcase side covers require perfectly flat
sealing surfaces, precise bolt-hole alignment and consistent wall
thickness to prevent oil leakage and ensure reliable engine
assembly; any dimensional deviation will cause gasket compression
inconsistency, oil seepage and assembly failure. This 280T
equipment realizes one-piece high-precision forming of side cover
bodies, sealing flanges and mounting boss structures, ensuring
every finished aluminum crankcase side cover meets consistent
functional and assembly standards.
The machine adopts a reinforced medium-tonnage frame structure
equipped with high-strength tie bars, enlarged wear-resistant steel
pins and thickened machine platens engineered for stable 280-ton
clamping force. This rigid architecture delivers exceptional impact
resistance and load stability during high-pressure cold chamber die
casting, minimizing mold deflection and micro-vibration during
precision forming. For crankcase side cover production, it
guarantees consistent sealing surface flatness, uniform wall
thickness and accurate bolt-hole positioning across every
production cycle. The robust construction suppresses long-term
mechanical deformation, extends equipment service life and fully
supports non-stop high-volume production of medium-sized aluminum
engine components.
At its control core is a genuine German PLC system paired with a
full-color human-machine interface touchscreen, enabling real-time
precise monitoring and adjustable control of injection speed and
pressure. Advanced closed-loop control technology delivers fine
graded regulation throughout the entire filling cycle, ensuring
complete, clean formation of thin sealing flanges, bolt mounting
bosses and internal rib structures without cold shuts or porosity
defects. This guarantees reliable gasket sealing performance and
stable assembly accuracy for every aluminum crankcase side cover.
The simplified electrical circuit design maintains stable, reliable
operation even in high-temperature workshop environments, and the
built-in fault display function quickly identifies electrical
system abnormalities to minimize unplanned downtime.
The hydraulic system operates on dual-proportional control
architecture to realize fully programmable multi-stage injection
and low-pressure buffered mold clamping, which protects delicate
bolt-hole core pins and precision sealing-surface mold cavities
from impact damage. All hydraulic seals are sourced from premium
European or Japanese brands, ensuring long-term leak-free, stable
performance under continuous 280-ton operation. A hydraulic die
height adjustment system enables fast, labor-saving mold
installation and changeover, reducing setup time for different
crankcase side cover sizes and engine models. An automatic pressure
relief energy-saving function effectively cuts unnecessary
hydraulic energy consumption during continuous operation.
The clamping and die height adjustment mechanism ensures uniform
stress distribution across the platen and stable mold positioning,
avoiding sealing-surface warpage and bolt-hole misalignment in
crankcase side covers. The injection unit with high-flow valves and
a precision piston accumulator delivers consistent injection
performance that fully fills complex multi-cavity side cover molds.
A high-efficiency oil cooling system maintains stable hydraulic
temperature during long-shift production, supporting a reliable
service life of 15 to 20 years. An optional mold sweeping robotic
arm is available to upgrade production automation.
