Types of Plastic Injection Moulds Manufactured by I Tech Moulds, Chennai!

Plastic injection molding is a versatile manufacturing process that can produce a wide variety of plastic parts and components. Here are some common types of plastic injection molds used in the industry:

1. Single Cavity Molds: Single cavity molds are the simplest type of injection molds, producing one part per cycle. They are typically used for low-volume production or when the part design is large or complex.
2. Multi-Cavity Molds: Multi-cavity molds have more than one cavity, allowing for the simultaneous production of multiple parts in each cycle. This significantly increases production efficiency and is ideal for high-volume manufacturing.
3. Family Molds: Family molds, also known as multi-component molds, are designed to produce multiple parts or components that are assembled together to form a single product. They are commonly used in the production of complex products with multiple integrated parts.
4. Hot Runner Molds: Hot runner molds utilize a system of heated channels (runners) to deliver molten plastic material directly to each cavity of the mold. This helps to minimize cycle times, reduce material waste, and improve part quality by eliminating the need for sprues and runners.
5. Cold Runner Molds: Cold runner molds use a system of unheated channels (runners) to deliver molten plastic material to the cavities. While they are simpler and less expensive than hot runner molds, they can result in longer cycle times and increased material waste due to the need for runners and sprues to be removed from the finished parts.
6. Insert Molds: Insert molds are designed to insert metal or plastic inserts into the mold cavity before the injection molding process begins. This allows for the production of parts with embedded features or components, such as threaded inserts or metal reinforcements.
7. Overmolding Molds: Overmolding molds enable the injection molding of multiple materials or colors onto a single part. This process is commonly used to add soft-touch grips, ergonomic features, or aesthetic accents to plastic parts.
8. Prototype Molds: Prototype molds, also known as rapid tooling molds, are used to produce low-cost prototypes or small quantities of parts for testing and validation purposes. They are typically made from less durable materials than production molds and have shorter lifespans.
9. Stack Molds: Stack molds consist of multiple mold plates arranged in a vertical stack, allowing for the production of multiple parts or components in each cycle. This design maximizes production efficiency and is ideal for high-volume manufacturing of thin-walled parts.
10. Gas-Assist Molds: Gas-assist molds use compressed gas to assist in the injection molding process, allowing for the production of hollow or partially hollow parts with reduced sink marks, warpage, and cycle times.

These are just a few examples of the types of plastic injection molds available, each offering unique advantages and suited to different production requirements and applications.
