Jolt Squeeze Molding Machine is suitable for mass production of single molding plate or single molding box of medium and small sized castings, which can produce cope or drag. The machine adopts micro vibration compaction mechanism, large shock force and compaction strength. So it can meet simple or complex molding requirements without pre-shock. It is one of the indispensable tools for mechanized molding and has gradually replaced traditional manual moldling.
What Is A Jolt Squeeze Molding Machine?
A jolt squeeze molding machine is a type of foundry equipment used to create sand molds for metal casting. It compacts molding sand around a pattern inside a flask using a combination of jolting (vertical impact) and squeezing (pressure application).
Jolt Squeeze Molding Machine Working Principle
A jolt squeeze molding machine is used in foundries to create sand molds for metal casting. It operates by compacting molding sand around a pattern to form a mold cavity.
- Jolting: The pattern and sand-filled flask are lifted and dropped suddenly, compacting the sand downward due to the impact.
- Squeezing: A squeeze head applies pressure from above, further compressing the sand to create a dense mold.
Why Jolt Squeeze Molding Machine Widely Used In Green Sand Moulding Process
The jolt squeeze molding machine is widely used in the green sand molding process because it efficiently compacts the sand, creating high-quality molds with minimal effort.
- Effective Sand Compaction
Jolting action settles the loose green sand around the pattern, ensuring even distribution.
Squeezing applies uniform pressure, increasing mold density and strength. - Cost-Effective and Simple Operation
Compared to other molding methods like high-pressure or vacuum molding, jolt squeeze machines are affordable and easy to operate.
They require less complex maintenance and lower energy consumption. - Suitable for a Wide Range of Castings
Works well for small to medium-sized castings in ferrous and non-ferrous foundries.
Produces dimensionally accurate molds with good surface finish. - Adaptability to Green Sand
Green sand (a mixture of silica sand, clay, water, and additives) remains moist and flexible, making it ideal for compaction through jolting and squeezing.
Unlike dry sand molds, green sand retains some plasticity, reducing defects like cracks. - Faster Production Rate
Automated or semi-automated versions increase productivity.
Ideal for mass production in foundries without needing extensive setup.
Jolt Squeeze Molding Machine Advantages

- Reduces defects in castings by improving mold strength.
- Faster and more efficient than manual molding.
- Suitable for small to medium-sized castings.
- Pneumatic components, long service life and convenient operatoin, effectively improves production efficiency.
- Optimized structure design. The square box frame structure greatly improves the rigidity of machine body.
- Micro vibration compaction process can greatly improve compaction strength and surface roughness to stabilize product quality. The hardness of sand molding can reach above HB90.
- The shock part is equipped with a buffer spring to effectively reduce the impact of the machine on the foundation.
- The pattern stripping mechanism adopts the cylinder, the crank, the connecting rod and the synchronous shaft to realize the synchronous lifting.
- Fully adopt pneumatic parts to achieve overall function of the controll part, easy operation and convenient maintenance.
Jolt Squeeze Molding Machine Application
- Suitable for small to medium-sized castings.
- Used in iron, steel, and non-ferrous metal foundries.
- Common in mass production settings.
Conclusion
Jolt squeeze molding machines provide an efficient, cost-effective, and reliable solution for green sand molding, making them the most widely used machine in small and medium-sized foundries.
