Industrial welding handle oven handle: subtle combination of material and technology

In modern industrial production, oven, as an important heat treatment equipment, plays an indispensable role in the manufacturing process. The handle of the oven is one of the most direct and frequent contact parts between the user and the oven. Therefore, how to design a beautiful, practical, durable and comfortable oven handle has become the focus of many manufacturers. This paper will discuss this topic from two aspects: material selection and production technology.

First, the choice of materials

1. High temperature resistance: Due to the high temperature inside the oven (generally above 200°C), it is required that its external accessories must have good heat resistance to ensure safe use. At present, there are several types of silica gel, plastic and metal commonly available on the market.

2. Insulation effect: In order to prevent the occurrence of scalding accidents, the thermal conductivity of the material itself should also be considered when making. Among them, silicone rubber products are the most ideal-it not only has excellent electrical insulation and chemical stability, but also has moderate softness and is easy to hold; But the disadvantage is that the cost is high and it is easy to age and deform.

3. Appearance quality and environmental protection attributes: In addition, considering the overall style of the product and the influencing factors on human health, it is recommended to give priority to the selection of non-toxic and harmless raw materials with bright and lasting colors for processing and preparation.

Second, the introduction of processing flow

1. Casting/stamping method: This is one of the most traditional and economical ways. The specific method is to pour molten liquid metal into the mold at high temperature, cool and solidify to form the required shape; Or use a high-speed press to shape and bend the plate. However, this method often needs a long time period and it is difficult to meet the requirements of high accuracy.

2. 3D printing technology: In recent years, with the development of computer-aided design software CAD and the decreasing price of related hardware facilities, the popularization trend is becoming increasingly obvious, and more and more enterprises have begun to try to use this means to quickly prototype and even mass produce parts. The advantages are obvious: flexible, convenient and fast operation without mold opening; The disadvantage is that the maximum size that can be supported at present is still limited, and the strength of the finished product is relatively low, which is not suitable for long-term heavy-duty applications.

3. Welding fixation method: it is suitable for the joints of various complex structures, such as T-shaped intersections or L-shaped corners. By heating, the two layers of thin sheets are closely attached to achieve the purpose of firm bonding. It should be noted that in order to ensure the stability and reliability of the final quality, it is necessary to fully prepare for preheating and accurately control the heat distribution before the actual operation to avoid bubble gap defects.

To sum up, only by selecting suitable raw materials and supplemented by advanced manufacturing technology can we make an ideal industrial oven handle assembly that combines functionality and artistry. I hope the above content can provide some reference value for the majority of peers!
