The automatic bismuth needle forming and packaging production line.

The automatic bismuth needle forming and packaging production line is an automated equipment used for the production of bismuth needles or bismuth beads, including a bismuth needle (bead) forming machine and a multi-layer tunnel type hot air dryer. This production line typically includes the following key steps: 1. Melting and conveying: The metallic bismuth is first melted in a melting pot, then pumped through a bismuth pump and delivered to the casting slot. 2. Forming and cooling: The molten bismuth liquid flows out from the casting slot's dispensing valve, passes through a former such as a stainless steel forming screen, and drips into a trapezoidal trough filled with cooling liquid (usually a mixture of water and additives). The formed bismuth needles slide onto a conveyor belt set at an incline, continuing to cool as they are gradually fed into the drying machine. 3. Drying and packaging: The bismuth needles enter a drying cylinder made of stainless steel plates rolled into a筒. The cylinder's entrance is equipped with an electric heater, and an internal spiral baffle is installed. The bismuth needles dry while moving forward inside the cylinder, also being dried by the hot air from the hot air blower. After drying, the bismuth needles flow into a packaging barrel for weighing and packaging. The advantages of this production line lie in its simple manufacturing process and equipment, which can directly process the molten bismuth liquid into the required bismuth needle products in one streamlined operation. The produced bismuth needles have a wide range of applications, such as in pharmaceuticals, metallurgical additives, electronics, and alloy development. The automated production line design helps to increase production speed, reduce energy consumption, and simplify the operation process. In addition, the equipment design also considers safety protection measures, such as leakage protection and overheating protection, to ensure the safety of the production process. Overall, the automatic bismuth needle forming and packaging production line is an efficient, energy-saving, and easy-to-operate equipment suitable for large-scale production of bismuth needle products.

What aspects can be considered when choosing a suitable hot air oven?

What aspects can be considered when choosing a suitable hot air oven? 1. Consider the size of the hot air oven. Enterprises need to consider the type, size, and quantity of items that need to be dried, which will determine the size of the internal space of the oven. Choose appropriate internal dimensions based on the size and quantity of the samples or items to be processed, taking into account the growth in demand and leaving a certain margin for simultaneous baking; We also need to consider the size of the space for storing the oven and determine the external size and shape of the oven. 2. It is necessary to consider whether a tray needs to be installed inside the oven. Determine whether to install additional trays inside the oven and choose different types of trays based on the size and shape of the dried items, as well as considering whether gaps are needed for baking. Conventional trays include grid trays, flat trays, and perforated trays. 3. Consider the function of a hot air oven. Due to the different products in different industrial industries, the required uses of hot air ovens are also different. If a dust-free environment is required, consider a dust-free oven; if nitrogen is needed, consider an oxidation free oven; if electronic components need to be packaged and baked, consider a dust-free oxidation free oven; if long-term baking is required to save time and energy, consider an energy-saving high-temperature oven; and if there are flammable, explosive, or volatile industrial products during high-temperature baking, consider an explosion-proof oven. The common temperature range of a hot air oven is also crucial. Different materials and processes require different temperature conditions, and the commonly used temperature and maximum temperature range are determined based on the products that need to be baked. 5. It is also important to pay attention to the temperature control accuracy of the oven. Accurate temperature control can ensure the consistency and stability of the drying effect, and high-precision temperature controllers can more accurately control the temperature inside the oven, meeting the strict temperature control requirements of experiments and processes. Ensuring good temperature uniformity inside the oven is crucial for the accuracy of the test results. Temperature stability is equally important to avoid adverse effects of temperature fluctuations on the sample. 6. Safety performance, equipped with over temperature protection, overload protection, leakage protection and other safety functions to ensure the safety of operators and equipment. If the oven experiences overheating during operation, the overheating protection device can promptly cut off the power supply to prevent accidents. 7. Brand and after-sales service are also important. Choosing a brand with a good reputation and comprehensive after-sales service can ensure that you have no worries during use. I hope these purchasing tips can help you choose the right precision oven for your business, making production more efficient!

MOL series dust-free oven Clean oven Installation, use and maintenance tips

MOL series dust-free oven Clean oven Installation, use and maintenance tips 1、 Installation location requirements: 1. A level and tidy floor is required; 2. Do not expose to flammable or corrosive gases; 3. Try to avoid direct sunlight and keep the ambient temperature below 40 ℃; 2、 Power installation requirements: 1. Connect the power according to the power specifications specified on the equipment nameplate; 2. The voltage fluctuation rate is within ± 5% of the rated value; To avoid electric shock accidents, the machine itself must be grounded (according to the third grounding method of the electrician regulations, the grounding resistance should be below 100 Ω); 4.

Check whether the delay device is accurate and whether the error is allowed.

The role of non oxidizing oven in electron beam evaporation polyimide (PI) coating process

Electron beam evaporation is a high vacuum coating technology that can prepare coatings of metals, alloys, ceramics, and other materials on various surfaces, with high film formation rate and excellent coating quality. More and more researchers are applying electron beam evaporation technology to surface modification of polyimide materials to improve their adhesion with other materials. Using high-speed electron flow to concentrate and heat a certain point of the film material, causing its temperature to rise and sublimate and deposit on the substrate. This technology avoids the problem of direct contact between the film material and the vapor deposition raw material in traditional vapor deposition technology, which can easily cause mutual mixing, as well as the problem of some film materials being unable to be deposited by vacuum thermal vapor deposition due to their high melting points.
