Product Description

This Electric Furnace for Efficient Die Casting Automation is not just a melting device—it’s a solution tailored to solve the core pain points of die casting enterprises: high energy costs, unstable melting quality, and low automation efficiency. Inspired by the feedback from over 500 die casting factories we’ve cooperated with, we found that most enterprises struggled with inconsistent metal melting (leading to 15-20% of waste products) and skyrocketing electricity bills. To address these issues, our R&D team spent 18 months optimizing the heating structure and control system.

The furnace’s exterior features a high-temperature-resistant cold-rolled steel shell—smooth to the touch, free of sharp edges, and able to withstand long-term exposure to 80℃ workshop temperatures without deformation. When in operation, it emits only a soft hum (below 65 decibels), far quieter than traditional fuel-fired furnaces that roar at over 90 decibels, making the workshop environment more comfortable for workers. Inside, the high-purity alumina fiber insulation layer locks in heat tightly, so you won’t feel excessive heat even when standing 30cm away from the furnace body. Every detail, from the ergonomic control panel (with clear, anti-glare buttons) to the anti-leakage power interface, is designed to make daily use smoother and safer.

Product Features & Highlights

• Exceptional Energy Efficiency: Adopts a dual-circuit electric heating design, which converts 92% of electrical energy into heat—25% higher than the industry average (around 73%). This means for a die casting factory producing 500kg of aluminum parts daily, the furnace can save about $300 in monthly electricity costs.

• Precise Temperature Control: Equipped with a PID intelligent temperature controller, the temperature fluctuation range is within ±2℃ (from 300℃ to 1200℃). Unlike traditional furnaces that often have temperature deviations of ±10℃, this precision ensures the metal alloy maintains stable chemical properties, reducing waste products caused by over-melting or under-melting.

• Full Automation Compatibility: Features a standard RS485 communication interface, which can be seamlessly connected to die casting production lines (such as robotic arms and conveyor belts). It can automatically adjust the melting speed according to the production line’s material demand, eliminating the need for workers to manually feed or adjust parameters—saving 2-3 labor hours per shift.

• Durable & Low-Maintenance Construction: The heating element uses imported Kanthal A1 alloy, which has a service life of up to 5000 hours (twice that of ordinary domestic heating elements). The furnace lining is made of high-strength refractory castable, which resists corrosion from molten metal and only needs to be inspected once every 6 months (instead of monthly inspections for cheaper furnaces).

• Enhanced Safety Protection: Integrates 7 safety mechanisms, including over-temperature alarm (triggers when temperature exceeds 1250℃), power leakage protection (responds within 0.1 seconds), and furnace door interlock (cuts off heating when the door is open). These features have helped our customers avoid all safety accidents related to furnace operation in the past 3 years.

Application Scenarios

This electric furnace is a perfect match for various die casting scenarios, solving specific problems for different users:

• Automotive Die Casting Plants: Used to melt aluminum alloys for producing engine parts (e.g., cylinder heads) and chassis components. Its stable temperature control ensures the parts have uniform density, reducing the risk of cracks during vehicle operation.

• Consumer Electronics Factories: Ideal for melting zinc alloys to make phone casings and laptop frames. The furnace’s small size (for 50-100kg capacity) fits in compact workshop spaces, and its low noise won’t interfere with precision assembly lines nearby.

• Hardware & Sanitary Ware Manufacturers: Suitable for melting magnesium alloys for making faucet handles and door hinges. The furnace’s fast melting speed (melts 100kg of magnesium in 45 minutes) meets the high-volume production needs of these industries.

• Custom Die Casting Workshops: With customizable capacity (50kg-500kg), it can adapt to small-batch, multi-variety production. For example, a workshop making custom aluminum molds can switch between melting 80kg of aluminum for small molds and 300kg for large molds without replacing equipment.

Core Advantages (Solving Customer Pain Points)

• Reduces Production Costs: The 92% energy efficiency cuts electricity expenses, and the 5000-hour heating element reduces replacement costs. A customer in Guangdong reported saving over $4,000 in annual maintenance and energy costs after replacing their old furnace with ours.

• Improves Production Efficiency: The automatic compatibility with die casting lines eliminates manual waiting time. A zinc die casting factory producing 2000 phone casings daily increased output by 15% (300 more casings) after using this furnace, as it no longer needed to pause the line for manual feeding.

• Ensures Product Quality: The ±2℃ temperature precision reduces waste rates. A automotive parts customer saw their waste rate drop from 18% to 5%—saving 225kg of aluminum (worth $450) per week.

• Simplifies Operation & Maintenance: The touchscreen control panel is easy to learn (new operators can master it in 2 hours), and the 6-month inspection cycle reduces downtime. A small workshop owner said they used to spend 8 hours monthly on furnace maintenance, but now only spend 2 hours every 6 months.

Usage & Maintenance Guide

• Usage Steps:

1. Check the power supply (ensure 380V/50Hz) and insulation layer (no cracks) before starting.

1. Add the metal material (cut into small pieces for faster melting) through the furnace door—do not exceed 80% of the furnace capacity.

1. Set the target temperature on the touchscreen (e.g., 750℃ for aluminum) and press "Start". The furnace will automatically heat up, with real-time temperature displayed on the screen.

1. Once melted (indicated by the "Melting Complete" alarm), open the discharge valve to release the molten metal into the die casting machine.

1. After use, press "Stop", turn off the power, and clean the furnace door (wipe with a dry cloth) to remove residual metal scraps.

• Maintenance Tips:

1. Every 6 months: Inspect the heating element (replace if there are signs of oxidation or breakage) and the refractory lining (repair small cracks with refractory cement).

1. Monthly: Clean the air filter of the forced cooling system (use compressed air to blow away dust) to ensure good heat dissipation.

1. Weekly: Check the safety interlock (test if the heating stops when the furnace door is opened) to avoid safety risks.

1. Avoid overloading the furnace (never exceed 80% capacity) or setting temperatures above 1200℃, as this will shorten the heating element’s life.
