What Is Silicone Dripping Dispensing Molding？
Silicone Dripping Dispensing Molding is a specialized process that uses highly durable and adaptable silicone to create various products with precision and detail. This technique involves dispensing a liquid silicone into a mold, which then hardens or “cures” to take the shape of the mold.
This process differs from other moulding types due to silicone’s unique properties. Silicone can withstand high temperatures, is resistant to many chemicals, and has excellent electrical insulation properties, making it a great choice for a variety of applications. The “dripping” or “dispensing” refers to the method of application, where the liquid silicone is carefully and precisely dispensed into the mold.
This allows for much control and precision in molding, making it possible to create intricate designs and shapes that may be difficult or impossible to achieve with other materials or methods. Once the silicone has been dispensed, it is left to cure, solidifying into the desired shape. This makes Silicone Dripping Dispensing Molding an innovative and powerful technique in the field of manufacturing.
Silicone Dripping Molding Process
While theoretically simple, the Silicone Dripping Molding process involves detailed steps handled with great precision and accuracy to create detailed and complex designs. Here’s a basic outline of how it works:
Step 1: Designing the Mold
The process begins with creating the mold according to the product’s specific requirements. This often involves using computer-aided design (CAD) software to ensure precision and accuracy. The mold is typically made of a durable material that can withstand the high temperatures required for silicone curing.
Step 2: Preparation of Silicone
Silicone comes in two parts that must be mixed. The parts are usually referred to as Part A and Part B. Part A is the actual silicone, while Part B is the curing agent that triggers the silicone’s hardening process. The Liquid Silicone Rubber (LSR) material undergoes a vacuum-assisted air expulsion process to ensure a void-free composition. This is followed by the addition of pigments to achieve the desired color spectrum for the product. These parts are mixed together in a precise ratio to prepare the silicone for molding.
Step 3: Precise Programming and Silicone Dispensing
Leveraging advanced Precision Dripping molding technology, precise programming enables meticulous control over the dispensing parameters. With twelve operational dripping heads, the machine can simultaneously mold twelve identical cavities or manage up to four cavities with three distinct colors. This high level of automation reduces labor requirements, replacing the need for 4 to 6 workers. The system is equipped with twelve quick-function buttons for swift and seamless operation of different design configurations. The dispensing can be controlled in terms of the amount of silicone, speed, and the area covered, allowing for highly detailed and complex designs.
Step 4: Heat Curing
Once the silicone is dispensed into the mold, it undergoes a curing process. This typically involves exposing the silicone to high temperatures that accelerate the curing agent’s effect, causing the silicone to harden and take the shape of the mold.
Step 5: Demolding
After the silicone has fully cured and hardened, it is removed from the mold, a process known as demolding. The product is then inspected, and any excess material or flashing is removed.
Step 6: Post-Curing and Finishing
A post-curing process may be applied depending on the product and its intended use. It involves further heating to ensure complete curing and enhance the product’s properties. Lastly, finishing touches such as painting, printing, or assembly of multiple parts may occur.
Due to the precision and versatility of silicone, the Silicone Dripping Molding process can produce a wide variety of products in many industries.
Advantage of Silicone Dripping Molding
Silicone Dripping Molding boasts numerous advantages, making it a go-to choice for various industries. Let’s delve into some of the key benefits this process offers:
Precision and Detail: The controlled dispensing of silicone allows for very high levels of precision, making it possible to create intricate designs and shapes with great detail. Multicoloured. You can get 12 colours in one product without any printing.
Attraction: More attractive and cute as gifts for kids and Women
Efficiency: The ability to work multiple cavities at the same time or multiple colours in different cavities enhances production speed and efficiency.
Overall, the Silicone Dripping Molding process is highly effective for producing detailed, durable, and customizable products.
