Cast Aluminum Heater Manufacturer

-- Steady & Reliable Manufacturer --

Introduction

As a specialized cast aluminum heater manufacturer, Sinton Electric produces robust, high-performance heating solutions designed for optimal heat distribution and durability. Our cast-in heaters are made by embedding tubular heating elements directly into aluminum or bronze, creating a single, unified unit. This process ensures excellent thermal conductivity and eliminates air gaps, making them perfect for applications requiring uniform heating of flat surfaces, high wattage, and resistance to mechanical shock and corrosion.

SINCE 2001

Sinton Electric Co.,Ltd.

Sinton Group was created in Yancheng City, Jiangsu Province. Sinton Electric Co., Ltd. is one sub-company of the Sinton group which started its business in 2001, We have formed a comprehensive group with energy-saving heating products as the mainstay, including import and export trade. Sinton's production base is its subsidiary China Hopebond Eco-Tech Co., Ltd., which is a national high-tech enterprise. The self-built 60-mu factory is located in Tinghu Environmental Protection Industrial Park. It has a production plant of 20,000 square meters and an R&D center of 3,600 square meters. It focuses on technological innovation and brand creation. , Specializing in the production of explosion-proof and non-explosion-proof heaters, air duct heaters, pipeline heaters, circulation heaters, electric drying machines, heat-conducting oil furnaces, Electromagnetic coil heaters, and all kinds of electric heating elements, such as direct thermal energy providing element or preheater of project. The products are mainly suitable for high-temperature heating environments of 50-1000℃ and are widely used in environmental protection, medical treatment, coal mining, petroleum, chemical industry, textile, plastics, heating, agriculture, animal husbandry, and other fields, and to promote the development of Zero-Carbon Economy and green earth conversion.

Our Advantages

  • Superior Heat Uniformity: The casting process ensures perfect contact between the heating element and the heater body, providing exceptionally even heat across the entire surface.

  • Extreme Durability: The solid metal construction makes our cast heaters highly resistant to mechanical damage, vibration, and corrosion, ensuring a very long service life.

  • Complex Geometry Capability: Our casting process allows us to create heaters with complex 3D shapes, integrated cooling channels, and mounting features, providing a complete solution.

Payment & Shipping

We accept T/T and L/C for international orders. Given the weight and value of cast heaters, we typically recommend sea freight in robust, custom-built crates. We can also arrange air freight for urgent orders and work with your preferred freight forwarder.

Frequently Asked Questions

  • Q: What is the main advantage of a cast-in heater over a bolt-on heater?

  • A: The main advantage is heat uniformity and longevity. The cast-in design eliminates air gaps, ensuring efficient heat transfer and protecting the heating element from damage.

  • Q: Should I choose an aluminum or bronze casting?

  • A: Choose aluminum for applications up to 400℃ where excellent thermal conductivity is needed. Choose bronze for higher temperatures up to 550℃ or when the heater will be exposed to corrosive environments.

  • Q: Can you integrate cooling channels into the heater?

  • A: Yes, we can cast water or oil cooling channels directly into the heater body. This is ideal for applications requiring both heating and cooling, such as injection molding platens.

  • Q: What is the typical lead time for a custom cast heater?

  • A: Custom cast heaters involve tooling and a casting process, so the lead time is typically 4-6 weeks. This can vary based on complexity and order quantity.

  • Q: How precise can the dimensions of a cast heater be?

  • A: We can achieve very tight tolerances through post-casting machining. Please provide your required tolerances on your drawing, and we will manufacture to meet them.

  • Q: Are cast heaters repairable?

  • A: Due to the monolithic construction, the internal heating elements are not field-repairable. However, they are designed for extreme durability and longevity, minimizing the need for replacement.

  • Q: Can you mount terminal boxes or other electrical components directly to the heater?

  • A: Yes, we can design and machine mounting surfaces or brackets directly onto the casting to accommodate terminal boxes, switches, or other components.

  • Q: What surface finishes are available?

  • A: We offer a standard machined finish, a polished finish for better heat transfer and non-stick properties, and various coatings (e.g., anodizing, PTFE) for corrosion resistance.
