Product Introduction

Sintered vents are manufactured through the sintering process of powdered metals. They consist of parallel and straight micro pores that allow for the passage of air and gas purge. These vents, also known as mold sintered vents or mold gas vents, are commonly used for gas purging during aluminum high-pressure or low-pressure die castings and resin molding. They help eliminate air or gas trapped in the cavity, which can lead to defects in the final product. Our stainless steel sintered vents have undergone extensive testing and have proven to effectively purify air and gas during the molding process.

Features

Enhanced Air and Gas Purging: Sintered vents provide a greater number of micro pores compared to traditional exhaust plugs. This increased pore density allows for improved air and gas purging during the molding process. The parallel and straight micro pores in sintered vents effectively facilitate the escape of air and gas, ensuring a cleaner and more precise molding outcome. This can significantly reduce the risk of defects and improve the overall quality of the final product.

Extended Work Life: Sintered vents have superior durability and a longer work life compared to traditional exhaust plugs. They are produced using a sintering process of powder metals, which enhances their impact resistance and heat resistance. This means that sintered vents can withstand the demanding conditions of the molding process for an extended period without losing their functionality. Their longevity translates to cost savings and reduced downtime for mold maintenance and replacement.

Excellent Corrosion Resistance: materials exhibit excellent corrosion resistance, ensuring that the vents can withstand corrosive elements present in certain molding processes or environments. This corrosion resistance prolongs the lifespan of the vents and maintains their effectiveness over time.

Easy Cleaning and Replacement: Sintered vents are designed with smooth vent holes and high precision outer diameters. This makes them easy to clean when necessary, ensuring optimal performance and preventing any blockages that may affect the molding process. Additionally, the precise dimensions of sintered vents enable straightforward replacement. When a vent needs to be replaced due to wear or damage, it can be easily removed and a new vent can be installed without significant disruptions to the production line.

Applications

1. Injection Molding: Stainless steel sintered vents are widely used in injection molding processes. They are installed in injection molds to allow the escape of trapped air and gas during the filling phase. By ensuring proper venting, sintered vents help prevent defects like voids, sink marks, or surface blemishes in the molded parts.

2. Die Casting: Stainless steel sintered vents are also utilized in high-pressure die casting processes. They are incorporated into the die to facilitate the release of air and gas during the molten metal injection. Proper venting with sintered vents improves mold filling, reduces porosity, and enhances the overall quality of the cast parts.

3. Blow Molding: Blow molding processes, used for manufacturing plastic bottles, containers, and hollow products, benefit from stainless steel sintered vents. These vents enable efficient evacuation of trapped air from the mold cavity during the blow molding process. By preventing air entrapment, sintered vents contribute to uniform wall thickness, reduced defects, and enhanced part strength.

4. Rotational Molding: Stainless steel sintered vents are employed in rotational molding, a process used to produce large, hollow plastic products such as tanks, containers, and playground equipment. Sintered vents ensure proper venting of air and gases, which is vital for achieving uniform wall thickness, minimizing voids, and improving the structural integrity of the final product.

5. Thermoforming: Thermoforming processes, which involve heating and shaping plastic sheets into various products like trays, packaging, or automotive components, utilize stainless steel sintered vents. These vents assist in the release of trapped air during the heating and forming stages, resulting in improved surface finish and reduced defects in the formed parts.

6. Resin Transfer Molding (RTM): In RTM processes, where liquid resin is injected into a closed mold to produce composite parts, stainless steel sintered vents play a critical role. They enable the escape of air and gas during resin injection, ensuring complete resin impregnation of the reinforcing fibers and minimizing the risk of voids or delamination in the composite structure.

7. Vacuum Casting: Stainless steel sintered vents are used in vacuum casting processes, which are commonly employed in rapid prototyping and small-scale production of plastic parts. Sintered vents aid in the evacuation of air and gases from the mold cavity during the casting process, resulting in high-quality replicas with improved surface finish and dimensional accuracy.

Package and Shipment

1. Sintered Filters are usually packed in cartons, wrapped in soft film, and fixed in a box filled with industrial foam cotton, and the outer baler is packed with plastic bags with no damage during transportation.

2. Wooden box export packaging can also be customized. The foam cotton can be filled and fixed, the external box is sealed, the bottom is specified, the whole packaging is processed, and the goods can be delivered to the customer's designated place without damage.
