Automatic Upgrades to Enhance Old Horizontal Flaskless Molding Machine Efficiency

Integrating automatic upgrades into an old horizontal flaskless molding machine is a game-changer for extending service life and improving productivity, as automatic features reduce manual intervention, minimize human error, and align the machine with modern sand molding machine and production lines.

• The most impactful automatic upgrades include adding variable frequency drives (VFDs), automated control systems, and robotic integration. VFDs allow the horizontal flaskless molding machine to adjust power output based on demand, reducing energy consumption by 15-20% and reducing wear on components .
• An automated PLC control system replaces outdated manual controls, enabling precise adjustment of molding parameters (e.g., sand flow, clamping pressure) and seamless coordination with sand molding machine—this not only improves mold quality but also reduces component strain. For high-volume production, integrating an industrial robot for workpiece loading/unloading eliminates manual handling, reducing machine downtime and component damage.

Sand Molding Machine Compatibility: A Key Consideration in Refurbishment

Ensuring the refurbished horizontal flaskless molding machine is compatible with existing sand molding machine is essential to maximizing efficiency, reducing downtime, and extending service life—many operators overlook this, leading to mismatched equipment and reduced productivity.

• Sand molding machine and horizontal flaskless molding machine work in tandem to produce high-quality molds, so their coordination directly impacts overall performance. During refurbishment, focus on aligning the sand feeding system of the horizontal flaskless molding machine with the output of the sand molding machine, ensuring consistent sand flow and moisture content (critical for mold quality) .
• Upgrade the horizontal flaskless molding machine’s sand recovery system to match the sand molding machine’s capacity, reducing waste and ensuring seamless integration.

Additionally, synchronize the control systems of both machines, allowing for centralized operation and real-time adjustments—this ensures that the horizontal flaskless molding machine and sand molding machine work in harmony, reducing strain on both pieces of equipment. Chong Jen Machinery’s experts evaluate the compatibility between old horizontal flaskless molding machine and sand molding machine during the pre-refurbishment assessment, recommending upgrades (e.g., adjustable sand flow, synchronized control) to ensure seamless integration. This compatibility-focused approach reduces machine strain by 25% and extends the service life of both the horizontal flaskless molding machine and sand molding machine.

Surface Refurbishment and Corrosion Protection for Longevity

Surface refurbishment and corrosion protection are often overlooked but critical steps in extending the service life of an old horizontal flaskless molding machine, as corrosion and surface damage can spread to internal components and compromise structural integrity.

• The harsh foundry environment—with sand, moisture, and high temperatures—accelerates corrosion, so proper surface treatment is essential. Start by disassembling external components, cleaning them thoroughly to remove rust, sand, and oil buildup; metal components with significant rust should undergo sandblasting to restore the base material.
• Apply a three-layer coating system: an epoxy primer to prevent corrosion, a polyurethane topcoat for durability, and a clear coat for added protection—this extends surface life by 5-7 years . Replace worn or damaged external parts (e.g., safety guards, control panels) to ensure the machine meets safety standards and operates smoothly.

Additionally, seal all joints and connections to prevent sand and moisture from entering internal components, which can cause premature wear. Chong Jen Machinery uses industrial-grade corrosion-resistant coatings and precision surface treatment techniques for horizontal flaskless molding machine refurbishment, ensuring the machine can withstand harsh foundry conditions. Our surface refurbishment process not only enhances the machine’s appearance but also protects internal components, extending overall service life by 30%.

Post-Refurbishment Testing and Maintenance Planning

Post-refurbishment testing and a structured maintenance plan are essential to ensure the refurbished horizontal flaskless molding machine operates at peak efficiency and maintains its extended service life. Testing should be conducted in three phases:

• First, a no-load test to verify component functionality, including automatic features and sand feeding system operation.
• Second, a partial-load test to check coordination with sand molding machine and adjust parameters for optimal performance.
• Third, a full-load test to simulate real production conditions, monitoring key metrics like mold quality, energy consumption, and component temperature . Any issues identified during testing—such as uneven sand flow or automatic control malfunctions—should be addressed immediately.
• After testing, establish a routine maintenance plan tailored to the refurbished horizontal flaskless molding machine, including daily cleaning, weekly component inspections, and monthly lubrication. This plan should also include regular checks of compatibility with sand molding machine, ensuring seamless operation.
