What are the types of molds in injection molding
1.Two-Plate Mold:Also known as a single-cavity mold, it's the simplest mold type. It consists of two plates that open and close to form a single cavity for the part. After the part is formed, the mold opens, and the part is ejected.
2.Three-Plate Mold:This type adds an extra plate, the runner plate or dividing plate, between the two main plates. This allows for more complex parts with additional features like multiple undercuts or internal threads.
3.Hot Runner Mold:The runner system (channels through which molten plastic flows) in this mold is kept at an elevated temperature. This prevents the plastic in the runners from solidifying, reducing waste and improving efficiency.
4.Cold Runner Mold:The runner system is not heated in this mold. The plastic in the runners solidifies and needs to be removed and recycled, potentially leading to some material wastage and increased cycle times.
5.Runnerless Mold (Hot Tip Mold):This mold eliminates the need for a traditional runner system by using a hot tip or valve gate at each cavity. It minimizes wastage and is suitable for high-precision molding.
6.Insulated Runner Mold:Similar to a hot runner mold, but with insulated runners to maintain temperature and prevent material from solidifying in the runners.
7.Semi-Hot Runner Mold:This mold combines elements of hot and cold runner systems, using heated sprue bushings and insulated runners to achieve a balance between reduced wastage and cost-effectiveness.
8.Multi-Cavity Mold:It contains multiple cavities, allowing for simultaneous production of multiple identical parts in a single mold cycle. This is ideal for high-volume production.
9.Family Mold:This mold type allows for the production of multiple different parts that are related or similar in a single mold cycle, optimizing production efficiency.
10.Stack Mold:This mold consists of two or more mold halves stacked vertically. Each mold half opens in the opposite direction of the one above or below it, enabling higher production rates for small parts.
11.Collapsible Core Mold:Used for creating parts with complex internal features or undercuts. The core is designed to collapse, allowing the part to be removed without damaging it.
12.Unscrewing Mold:Specifically designed for producing threaded parts, it incorporates a mechanism to rotate the core or cavity section to unscrew the threaded part from the mold after molding.
13.Gas-Assist Mold:Nitrogen gas is injected into the mold after the plastic has partially filled the cavity. This helps hollow out thick sections of the part and reduce warping.
14.Insert Mold:Accommodates inserts like metal components or pre-formed parts, which are placed into the mold before injection. The molten plastic surrounds and bonds to the inserts.
15.Overmolding Mold:Creates parts with multiple layers, typically combining soft and rigid materials. This is used for improved grip, aesthetics, or functional requirements.
16.Rotational Mold (Rotomold):Used for hollow parts like tanks, containers, and large items. The mold rotates on multiple axes, coating the interior of the mold with plastic.
Injection molding is a widely used manufacturing process for producing plastic parts in large volumes. Common injection molds are designed to create a variety of products with different shapes, sizes, and features.

Hopo mold products have three series:
A.Home Appliance Mould
A home appliance mold, also known as a household appliance mold, is a type of injection mold specifically designed for producing plastic components or parts that are used in various home appliances. Home appliances encompass a wide range of electrical and mechanical devices that are commonly used in households, such as refrigerators, washing machines, microwaves, vacuum cleaners, and more. These appliances often consist of multiple plastic parts that serve functional, structural, and aesthetic purposes.
A motorcycle mold, also referred to as a motorbike mold or motorcycle part mold, is a type of injection mold that is designed to manufacture plastic components or parts used in the production of motorcycles. Motorcycles are complex vehicles made up of various parts, and many of these parts can be produced using injection molding technology.
An automobile mold, also known as an automotive mold or car part mold, is a type of injection mold designed for manufacturing plastic components or parts used in automobiles. The automotive industry relies on injection molding to produce a wide range of plastic parts that contribute to the functionality, safety, aesthetics, and overall design of vehicles.
