KRMOLD has accumulated rich experience in plastic injection mold R&D and manufacturing, possessing strong technical support and a talented team to meet the ever-changing market demands of its customers. KRMOLD is committed to the design and manufacture of plastic injection molds to ensure high-quality, high-efficiency manufacturing solutions for customers. This video will introduce you to the four most commonly used molding processes in KRMOLD plastic injection mold manufacturing: two-platen injection molds, three-platen injection molds, insert molding, and overmolding.
Two-platen Injection Molds: Two-platen injection molds are the most commonly used plastic injection mold design, offering advantages such as simple structure, low cost, and easy maintenance. They work by using two flat plastic injection molds for injection; one plastic injection mold injects the plastic, while the other holds pressure and cools the plastic injection mold. Due to their simple design, two-platen injection molds are suitable for the production of most products, especially single-material parts.
Three-platen Injection Molds: Three-platen injection molds add an extra separator plate, facilitating the handling of more complex parts. The design of three-platen injection molds allows plastic to flow in a smaller space, ensuring good filling even for complex-shaped parts. This type of plastic injection mold allows for multiple gates during manufacturing, significantly improving production flexibility and material utilization. Due to its greater complexity and flexibility, three-plate injection molds are typically used to produce high-precision parts, especially in industries requiring stringent standards such as automotive, medical, and electronics.
Insert Molding: Insert molding is a process where metal or other materials are inserted into a plastic injection mold. During manufacturing, plastic encapsulates the inserted material as it is injected, forming a composite structure. This process is particularly suitable for products that require combining multiple different materials, such as automotive parts and electronic component assembly.
Overmolding: Overmolding focuses on covering an existing structure with a layer of plastic. This type of plastic injection mold has a wide range of applications, enabling multiple functions such as decoration, protection, and performance enhancement. Overmolding is commonly used in the production of surface treatments for home appliances and automotive trim parts, giving products an aesthetically pleasing appearance while maintaining structural strength.
