Professional Manufacturer of Electric Hot Plates – ET Series High Precision Digital Constant Temperature Heating Stage. Our company has devoted ourselves to the R&D and production of heating stages since 2008. As a well-known industry consensus, product quality and market positioning mainly depend on three core factors: first, the selection of core accessories; second, rational structural design; third, sophisticated manufacturing craftsmanship. We are a fully self-developed hot plate manufacturer without resale trading, so factory-direct supply guarantees stable product quality and complete after-sales service.

1.1 Premium Grade Core Components

We adopt genuine high-precision digital temperature controllers from Xiamen Yudian, a highly reputable brand with reliable performance and up to 36 months maximum warranty. The core heating elements are stainless steel heating tubes made of imported resistance wire, whose service life is over twice that of ordinary tubes under identical operating conditions. Models rated for 450℃ adopt fully imported heating tubes for superior quality and longer lifespan. The entire housing is made of SUS304 stainless steel, with far superior rust resistance compared to painted iron sheet or SUS201 material.

1.2 Iterative Optimized Structural Design

We consistently focus on refining and perfecting heating stage products. After years of research and iteration, our hot plate series has undergone multiple generations of upgrades, featuring more reasonable internal structure, streamlined appearance and ultra-precise temperature control.

1.3 Standardized Professional Assembly Craftsmanship

All assembly technicians hold official electrician certificates. Internal wiring layout is neat and standardized; all cables adopt national standard halogen-free high-temperature fire-resistant wires.

We are direct manufacturer rather than distributors, supporting full non-standard customized sizes. Lead time for custom orders: 3–7 working days. Brand: ETOOL, accurate temperature control without overshoot.

1. LED industry: aluminum substrate soldering, LED chip welding and rework repair.
2. LCD & mobile touch screen maintenance: flex cable removal, touch panel adhesive stripping.
3. Laboratory heating equipment & thermal testing; essential instrument for biology, genetics, medical hygiene, environmental protection, biochemistry, analytical labs and academic research.
4. Baking & drying of constant-temperature test samples across all industrial sectors.
5. Preheating, desoldering and repair of electronic components & SMD parts in electronics manufacturing.
6. Constant temperature heating for glue dispensing & encapsulation in all electronics industries.
7. Mold core preheating for mold manufacturing factories.

1. Connect power supply and turn on main power switch. Solid green power indicator lamp confirms power input.
2. Turn on heating switch to start operation. Solid red heating lamp = continuous temperature rise; flashing red lamp = constant temperature mode with intermittent heating cycles.
3. After use, turn off heating switch first to stop heat output. Green power lamp remains lit as safety warning – do not touch hot surface. Wait at least 1 hour for full cooling before cutting main power supply.

1. Rated voltage AC220V; must use grounded three-hole socket equipped with residual current protection switch.
2. Untrained personnel shall not open machine casing or arbitrarily modify internal wiring.
3. Do not touch heating plate surface directly by hand to avoid scald injury.
4. Cut off full power supply when leaving unattended or long-term idle storage.
5. This unit is equipped with air cooling system; never block side air intake vents.

8.1 Official Warranty Policy

1. 1-year free full-unit warranty under normal usage excluding man-made damage; heating tubes covered under separate 6-month warranty.
2. Paid lifetime maintenance service available after warranty expiration.

8.2 Important Operation Reminders

1. Fully insert power cord into rear socket and ensure tight connection; loose contact may cause sparking and damage power jack.
2. Initial heating may overshoot set temperature by 3–5℃ and stabilize after several minutes; this design improves overall surface temperature uniformity.
3. Residual machining oil inside screw holes will vaporize under high temperature, generating white smoke and slight odor — this is normal and will fade after several hours of operation.
4. Minor clicking sounds during heating are caused by thermal expansion & contraction of heating tubes against mounting plates; no safety risks, safe for continuous operation.
5. All units complete 24-hour continuous aging test before factory shipment. Unauthorized modification of internal parameters voids warranty; our company shall not bear liability for equipment failure or personal injury caused by improper manual parameter editing.

Warranty statement: Heating tubes carry 6-month warranty, full machine 1-year warranty. For technical issues, you may first consult our online engineers for remote troubleshooting, or send the unit back to our factory for repair. Shipping fees covered by factory within warranty period; customer bears freight after 1 year of shipment.
