Product Description

‌Industrial Applications

The system is designed for sand core manufacturing of small-to-medium workpieces in:

Plumbing fixtures and fire protection equipment
Pump valves & hardware components
Automotive/motorcycle accessories
Hydraulic/pneumatic systems
Product Output Profile‌

Specializes in producing precision sand cores for:

Valve bodies and faucet castings
Hydraulic component housings
Hardware fittings requiring dimensional accuracy
Automated Production Sequence‌

1. Sand Loading Phase‌

Shooting cylinder aligns below sand reservoir
Gate mechanism opens for material intake
Sealed cylinder transports sand to mold station

2. Mold Engagement‌

Dynamic and static mold halves achieve zero-gap alignment
Simultaneous core rod elevation

3. High-Pressure Injection‌

Injection nozzle seals against mold cavity
Solenoid-controlled sand discharge

4. Thermal Curing‌

Retracted nozzle initiates heating cycle
Programmable temperature gradients ensure complete curing

5. Demolding Process‌

Core rods retract vertically
Moving mold plate withdraws with automatic ejection
Manual extraction of finished sand core

6. Smart Replenishment‌

Preset shot counter triggers auto-refill
Optional core rod deactivation mode

Key technical highlights:
√ ‌Closed-loop material handling‌ eliminates manual intervention
√ ‌Electro-pneumatic controls‌ ensure injection consistency
√ ‌Dual-mode operation‌ supports batch or continuous production

Specification

Structural Framework
