Aluminum Brazing Furnace | Batch Oven
LPR Global provides batch type aluminum brazing furnace. The brazing furnace is available as a box type oven or can connected to produce a semi-continuous brazing process. The semi-continuous brazing line is done by linking three chambers: preheating chamber, brazing chamber, and cooling chamber for an effective heat transfer.
This aluminum brazing batch furnace is ideal for brazing larger aluminum parts. Its compact design allows for efficient space utilization, while providing ideal brazing results.
Specifications are available upon request and customized as required.
Stainless Steel Brazing | Annealing Furnace
LPR Global’s stainless steel brazing furnace is a multi-functional furnace that can carry out brazing, and annealing, saving production and machinery costs.
This stainless steel brazing furnace operates on a mesh belt to maintain a high-speed, continuous brazing process for stainless steel, copper alloys, and other metals that require a light atmosphere for brazing.
Features
Applications
Extensive applications in automotive stainless steel parts, copper-based parts (e.g pipes), brazing, and bright annealing for automotive parts.
Steel Brazing Furnace | Energy Efficient
LPR Global provides brazing furnace for brazing steel as well as ferrous and copper alloy products. The use of embedded exothermic gas generator in the heating section of this brazing furnace effectively utilizes heat and energy generated from the gas generator. Compared to other gas generators that require large volume of water for cooling, LPR Global’s brazing furnace efficiently reduces water and energy requirement.

Preheating Furnace | Convection Type
This preheating furnace is used for preparing metal parts before undergoing brazing or heat treatment. LPR Global’s compact preheating furnace uses forced circulation to ensure a rapid preheating process.
Bright Annealing Furnace | Roller Hearth Type
Our bright annealing furnace provides continuous annealing process through roller hearth rotation to support a higher production capacity. Generated energy is recycled back into preheating the work pieces. Read more about how our bright annealing furnace saves operating costs and energy in the bright annealing furnace tab.

Carburizing Furnace | Case Hardening Furnace
Carburizing furnace runs in a continuous process with reduced frictional resistance, and are the most suitable for large quantity productions of low carbon steel parts of high alloy steel parts such as fasteners, and other small components. Our carburizing furnace features optimized quality at the lowest expense by saving generated gas, using atmosphere control technology, oxidation prevention, and utilization of high temperature.

Bright Annealing Furnace | Roller Hearth Continuous System
LPR Global’s bright annealing furnace allows annealing operations in a controlled atmosphere to minimize oxidation while relieving the internal stress and increasing ductility of the steel components. By applying controlled heat, the steel parts are heated, then cooled slowly in the continuous oven.
This bright annealing furnace has an embedded atmosphere gas generator which recycles generated energy from the atmosphere gas and uses it for preheating the next batch of parts before they are annealed. This process saves approximately 180 KW/hr for an annealing process of 2000 kg/hr and lowers the CO2 output by 27%.
In addition, although oxide scaling can be prevented in a typical bright annealing furnace, it is difficult to remove the temper color. LPR Global’s bright annealing furnace took this into consideration and implemented a specially designed spheroidizing furnace (cooling chambers) that allows heat treatment of metal coated parts.

Bright Annealing Furnace Applications
A bright annealing furnace is required to restore the ductility after cold forming, grinding, machining, bending, or drawing to relieve the stress built up from previous steps and to avoid cracking as the parts move on to the next manufacturing step that might use higher temperature.
Bright annealing can be applied to steel parts, as well as non-ferrous parts such as copper, aluminum, or brass material.
Common uses of Bright Annealing Furnace
- Bright annealing of steel pipes and stainless steel pipes
- Bright annealing of copper alloys
- For multiple controlled cooling sections – Spheroidizing and Porcelain furnace
Carburizing Furnace | Case Hardening
Carburizing furnace carburizes low carbon steel parts and high alloy steel parts in a continuous process to create a wear resistant surface while keeping the strength in the inner core of the parts.
Our standard carburizing furnace runs on a mesh belt conveyor with reduced frictional resistance, making it suitable for production of large quantity metal products such as fasteners including bolts and nuts, screws, and washers.
