According to the production process, hinges can be divided into stamping hinges and casting hinges. As the name suggests, stamping can be understood as a manufacturing process that uses an external force to forcibly change the structure of an object. Made into the desired shape, i.e. “stamped”. This manufacturing process has a short cycle and is convenient to manufacture, and is relatively inexpensive in terms of manufacturing cost. In the hinges of door hinges, stampings are used in the place where do not bear too much stress. .

Obviously the stamped parts look a bit thin and due to structural issues more of the parts are exposed to air which leads to possible intrusion of sand inside.

Casting is one of the oldest technologies of mankind. The initial application of casting can simply be understood as pouring molten metal into a mold, cooling it and shaping it. Great progress, a certain precision, all indicators such as temperature and hardness have reached extremely high requirements and standards.

Due to the higher cost of the manufacturing process, cast hinges are often used on boats to prevent rust and maintain their luster for a long time.

Among all the precision casting technology ,one of the most common investment casting is Silica Sol casting( also known as lost wax casting).

     The main process : select suitable investment materials (such as paraffin) to make investment molds; repeat the steps of dipping refractory paint and sprinkling refractory sand on the investment mold, hardening the shell and drying; then Melt the internal investment mold to obtain a cavity; bake the mold shell to obtain sufficient strength and burn off the residual investment material; cast the required metal materials; solidify and cool, and clean the sand after shelling to obtain high precision The finished product. According to product needs that various treatment , including heat treatment, cold working and surface treatment

     Silca Sol Investment Casting, the products are precise, complex, close to the final shape of the part, and can be used directly without processing or with little processing to save product costs for customers,It is an advanced casting process that is close to forming.

Dealing with stainless steel drain vents requires a multifaceted approach that considers functionality, design, and maintenance to ensure optimal performance and safety. Stainless steel, known for its durability and resistance to corrosion, is a preferred material in various settings, from yachts and ships to commercial and residential buildings.

When selecting a stainless steel drain, it’s crucial to consider the size and design compatibility with your existing drainage system. Different environments may have unique requirements for drain and vent systems. For example, in yachts and ships, the primary concern is discharging sewage gas, water, and oil efficiently. In contrast, in commercial settings like bakeries or food processing plants, the focus is on reducing bacteria and effective drainage​​.

Proper venting is critical in plumbing systems. Venting options like common vents, loop vents, and air-admittance valves (AAV) play vital roles in maintaining the system’s integrity and functionality. Common vents are suitable for fixtures that are close together, while loop vents are useful for island counters in kitchens where venting options are limited. AAVs are mechanical vents that help in situations where conventional venting is not feasible. They work by allowing air to enter the plumbing system when a partial vacuum is created, preventing the release of sewer gases​​.

In cases of blockages, it’s essential to address the issue promptly to prevent potential hazards and maintain cleanliness. Blockages can cause unpleasant smells, like the rotten egg scent often associated with sulfur bacteria or sewage contamination. Regular maintenance, such as using boiling water, white vinegar, or caustic soda, can help prevent and clear blockages. For more severe issues, such as cracked vents or significant clogs, professional assistance might be required​​.

Another aspect to consider is the structural integrity and design of the drainage system, particularly for large-scale installations like steel structures. Adequate venting and draining provisions are crucial to prevent issues such as air pocket formation, excess galvanizing buildup, and safety concerns. Balancing the need for sufficient venting and draining holes while maintaining the structural integrity of the steel member is a key consideration for designers and engineers​​.

In summary, dealing with stainless steel drain vents involves careful selection, proper installation, regular maintenance, and understanding the specific needs of your environment. It’s a balance of aesthetics, functionality, and safety, ensuring the system remains effective, hygienic, and visually appealing.
