INJECTION MOLDING APPARATUS AND INJECTION MOLDING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240033980 titled 'INJECTION MOLDING APPARATUS AND INJECTION MOLDING METHOD
Simplified Explanation
The patent application describes an injection molding apparatus that improves the mechanical properties and aesthetic characteristics of an article to be made at or near the melt lines of the article. The apparatus includes a mold body with a main cavity to contain primary molten polymeric material and a tank in fluid communication with the main cavity, which contains auxiliary molten polymeric material.
Key points of the patent/innovation:
- The apparatus includes a pressurized gas injector in communication with the tank to inject pressurized gas into the tank.
- The pressurized gas displaces part of the auxiliary molten polymeric material from the tank into the main cavity, preventing the entry of the pressurized gas into the main cavity.
- This prevents the formation of gas bubbles or voids in the main cavity, improving the mechanical properties and aesthetic characteristics of the article.
- The invention also relates to an injection molding plant and method for making an article using this apparatus.
Potential applications of this technology:
- Injection molding of plastic articles where the mechanical properties and aesthetic characteristics are critical.
- Manufacturing of high-quality plastic parts for automotive, aerospace, and consumer electronics industries.
- Production of complex plastic components with improved structural integrity.
Problems solved by this technology:
- Eliminates the formation of gas bubbles or voids in the main cavity during injection molding.
- Improves the overall quality and appearance of the molded article.
- Enhances the structural integrity and strength of the article, especially at or near the melt lines.
Benefits of this technology:
- Improved mechanical properties of the molded article, such as increased strength and durability.
- Enhanced aesthetic characteristics, including smoother surfaces and reduced surface defects.
- Increased production efficiency by preventing the need for post-molding processes to remove gas bubbles or voids.
- Enables the production of complex and high-quality plastic components.
Original Abstract Submitted
described is an injection molding apparatus including a mold body having an inner surface defining a main cavity to contain primary molten polymeric material, a tank in fluid communication with the main cavity which contains auxiliary molten polymeric material, a pressurized vas injector in communication with the tank to inject the pressurized gas into the tank to displace part of the auxiliary molten polymeric material from the tank into the main cavity to prevent entry of the pressurized gas into the main cavity. the invention also relates to an injection molding plant for making an article and to an injection molding method for making an article. the apparatus, the plant and method for the injection molding of polymeric material according to the invention improve the mechanical properties and the aesthetic characteristics of an article to be made at or near the melt lines of the article.
