The compression molding process of silicone wristband is like a key process that gives the product a soul, which directly determines the presentation effect and service life of the wristband pattern. In the process of transformation from raw materials to finished products, the fineness of the mold and the control of the molding process have a profound impact on the clarity and overall durability of each pattern.
As the core tool for compression molding, the quality of the mold plays a decisive role in the presentation of the pattern. The high-precision mold is carved by CNC machining technology, which can accurately reproduce every detail on the design draft, whether it is small text, complex graphics, or delicate lines, can be clearly and completely transferred to the silicone wristband. On the contrary, molds with insufficient precision will cause blurred edges and missing details of the pattern, making the originally carefully designed pattern lose its beauty and recognition.
Temperature and pressure control during the molding process are also crucial. The silicone raw material needs to soften at a suitable temperature to fully fill every corner of the mold and achieve accurate molding of the pattern. If the temperature is too high, the silicone will become hard and brittle due to excessive vulcanization, which will not only affect the touch, but also cause the pattern to deform; if the temperature is too low, the silicone cannot be completely cured, and the clarity and three-dimensional sense of the pattern will be greatly reduced. The size of the pressure directly affects the density of the silicone. If the pressure is insufficient, the silicone will not be able to fill the mold groove, and the pattern will easily be sunken and uneven; if the pressure is too high, the mold may be damaged, shortening its service life, and also causing adverse effects on the silicone material itself.
The demolding process seems simple, but it is actually a mystery. If the demolding operation is improper, it is very easy to damage the molded wristband and destroy the integrity of the pattern. Experienced operators will select the appropriate demolding agent according to the characteristics of the silicone, and master the appropriate demolding force and angle to avoid scratches, tears or deformation of the pattern due to brute force pulling. This process requires not only skilled techniques, but also an in-depth understanding of the characteristics of silicone materials.
The post-processing process after compression molding will further affect the clarity and durability of the wristband pattern. For example, through grinding, polishing and other processes, burrs and defects on the surface of the wristband can be removed to make the pattern smoother and more delicate; while surface treatment methods such as oil spraying and glue dripping can protect the pattern while enhancing its color saturation and three-dimensional sense, improving the overall visual effect, and making the pattern more wear-resistant and scratch-resistant in daily use.
In addition, the quality and formula of the silicone raw material itself complement the compression molding process. High-quality silicone raw materials have good fluidity and uniform vulcanization speed, which can better fit the shape and details of the mold. With the exquisite compression molding process, it finally presents a clear, beautiful and durable pattern. Even with advanced molds and processes, inferior raw materials are difficult to achieve the desired effect.
With the continuous advancement of science and technology, the compression molding process is also continuously innovating and optimizing. The application of new mold materials and the popularization of intelligent temperature and pressure control systems have provided more possibilities for improving the clarity and durability of silicone wristband patterns. In the future, we are expected to see more exquisite and durable silicone wristbands to meet people's increasingly diverse needs.
