Pneumatic Breakers in the Casting Industry – FAQs
What are pneumatic breakers used for in casting?
They are used to break molds, knock off sand cores, or remove risers and runners from cast parts.
Why use pneumatic breakers in foundries?
They offer high impact force, are reliable in harsh environments, and don’t produce sparks—important for safety.
Can they be used on hot castings?
Yes, many models are designed to work safely on hot or warm castings.
What tool bits are used?
Common bits include chisels, points, and flat spades—chosen based on the casting material and task.
Are there size options for different tasks?
Yes, from light handheld breakers for small parts to heavier models for large castings.
Do pneumatic breakers cause damage to cast parts?
If used correctly, they minimize damage; operator skill and bit choice are key.
How are they powered in a foundry setting?
Typically via centralized compressed air systems with pressure regulators.
How often do they need maintenance?
Regular lubrication and inspection are needed—especially in dusty, high-temp environments.
Are vibration and noise a concern?
Yes, proper PPE (anti-vibration gloves, ear protection) is recommended to protect workers.
Can robotic arms use pneumatic breakers?
Yes, some automated systems use mounted breakers for repetitive casting tasks.
Hydraulic Pump Stations – FAQs
What is a hydraulic pump station?
It’s a unit that generates hydraulic power to run machinery like breakers, presses, or clamps.
What role do they play in casting or foundry operations?
They power core removal tools, mold handling systems, trimming presses, and hydraulic breakers.
What types of pumps are used?
Piston, gear, or vane pumps depending on flow and pressure needs.
Can one pump station serve multiple tools?
Yes, if designed with sufficient capacity and proper flow control.
How is pressure controlled?
Via pressure relief valves, regulators, and control circuits.
What kind of hydraulic fluid is used?
Typically anti-wear mineral oils, but high-temp or fire-resistant fluids may be needed in foundries.
How do you cool the hydraulic fluid?
With heat exchangers, oil coolers, or fan-cooled systems, depending on duty cycle.
What maintenance is required?
Monitor fluid level/quality, clean filters, inspect hoses, and check for leaks.
Are there portable hydraulic pump stations?
Yes, mobile units exist for servicing or field operations.
How do you ensure safety in high-heat areas?
Use heat shields, fire-resistant hoses, and temperature-rated fluids/components.
