Introduction of Dual Injection, Precision Injection, and Micro Injection

Plastic products are ubiquitous in daily life, almost everywhere, from automobiles, electrical equipment, construction, medical devices to everyday items... plastic is an essential part of them all. Without plastic, people's lives would be profoundly impacted, like "a stone thrown into a pond, creating ripples that spread far and wide." Although closely related to our lives, we often don't fully understand the principles behind plastic formation. Common processing methods include injection molding, extrusion molding, and blow molding. Among these, injection molding is especially suitable for fine, high-volume, and complex products.

What is Injection Molding?

Injection molding is a common plastic processing method. The process involves heating the resin to a molten state, then injecting it into a mold designed according to the customer's specifications. After cooling and solidifying, the molded part is ejected. With the development of processing technology, traditional single injection molding has evolved into dual injection molding.

The Advantages of Dual Injection Molding Compared to Single Injection Molding:

Dual injection means that in a single injection molding process, a product with two different colors or materials can be formed in one step. Its advantages include:

Appearance Enhancement:

Increase the diversity of product colors, allowing for custom color combinations according to customer requirements, enhancing the visual effect of the appearance.

Reduction of Manual Assembly and Improvement of Production Efficiency

In traditional single injection molding, parts made of different materials need to be produced separately and assembled manually. With dual injection molding, the production process can be simplified, while also reducing the risk of human assembly errors.

Functional Enhancement

The plastic material with different textures can be added at specific locations based on the product's functional requirements to enhance the product's performance.

The shell of the rangefinder manufactured by our company, Chien Feng Yuan, is primarily made of a harder material, while the grip area uses a softer material to enhance its anti-slip functionality, significantly improving the tactile feel.

Additionally, the shell of the horizontal measuring instrument is also produced using a dual injection molding process, consisting of two materials: one is a hard outer shell, and the other is a hard material with a luminescent feature, providing extra visibility in low-light environments.

Striving for Excellence, Advancing Toward the Microscopic World

Precision Injection

To meet the demands for precision components in the millimeter to centimeter range, the role of precision injection molding technology is becoming increasingly important. The application of precision parts spans across automotive components, electronics, consumer goods, and medical devices.

Micro Injection

Compared to precision injection molding, micro injection molding is specifically designed for parts that can be reduced to the micrometer scale. Its application range includes medical devices, microelectronic products (such as sensors, micro connectors, and micro mechanical components), as well as thin films.
