Choosing the right injection mold for your project is crucial, as different mold types will directly impact production efficiency, product quality, and cost. Based on your needs and production scale, there are various types of injection molds available.
A single-cavity mold is a type of injection molding mold with a simple structure, producing only one part per injection cycle. While the production efficiency of this mold is lower, it generally has a lower cost, making it suitable for initial development, prototyping, or small-scale production.
In a multi-cavity mold, each cavity can be used to inject molten plastic, allowing multiple identical plastic parts to be produced in a single injection cycle. This mold design enables the production of more parts in the same amount of time, reduces the cost per product, and increases production efficiency, making it especially suitable for large-scale production.
A two-shot mold is a mold design used for the two-shot molding process. This molding technique allows two different materials to be injected into the same mold within a single production cycle, forming a single multi-material part. Common applications include dashboards, car door interiors, and mobile phone housings.
An insert mold is a mold design used for injection molding. This mold allows pre-made “inserts” to be placed into the mold, and then molten plastic is injected to form the final part. This molding process is suitable for producing composite parts made of metal and plastic.
Hot runner mold is suitable for mass production and the manufacturing of high-precision parts. This mold uses a hot runner system to deliver molten plastic into the mold cavities. The mold design and manufacturing are relatively complex and typically require a higher initial investment, but they significantly improve production efficiency, reduce waste, and enhance product quality.
Cold runner molds use a cold runner system to inject molten plastic into the mold cavities. As the plastic flows through the runner, it cools and solidifies, creating waste. While these molds are cost-effective to design and manufacture, they generate waste, have lower efficiency, and may affect part quality. While, with proper design and maintenance, they can operate efficiently and produce quality parts.
The manufacturing lead time for the injection molds we produce for our clients is typically 4 to 6 weeks, with the exact time depending on the complexity and requirements of the project. Throughout the production process, we provide weekly progress updates to keep clients informed and aligned with the timeline.
During the design phase, we work closely with you to ensure that all design requirements and technical details are clearly defined. We use advanced CAD/CAE design software to quickly and accurately complete the mold design, and through simulation analysis, we proactively identify potential issues, avoiding the need for design modifications later on.
We establish detailed time milestones for each project and assign a dedicated engineering team to oversee the process, ensuring that machining, fine engraving, and assembly tasks are completed on time. The progress of each step is updated in real-time to ensure that the project stays on schedule.
Throughout the manufacturing process, we provide regular progress updates to our clients, ensuring you are always informed about the project’s status.

The commonly used materials for plastic injection molds include the following:
Steel
Steel is one of the most commonly used materials in injection molds, especially for molds designed for long-term use. There are several types of steel, depending on the composition:
Aluminum
Aluminum molds are typically used for small batch production and prototype molds due to their light weight and good thermal conductivity, which can improve production efficiency. Aluminum molds are faster to process but less durable than steel molds, making them suitable for applications with fewer production cycles.
Copper
Copper is used in some specialized applications, particularly in molds that require high thermal conductivity. Copper molds can speed up cooling times, enhancing production efficiency.
Alloys
Alloy materials such as aluminum alloys and copper alloys offer good corrosion resistance and strength, making them suitable for molds with specific requirements.
Surface-treated Materials
High-precision molds may use materials with special surface treatments, such as chrome-plated steel or surface coatings, to enhance their wear resistance and lifespan.
Each material has its specific application scenarios, and the choice depends on factors such as product complexity, production volume, and the mold’s usage requirements.

Mold maintenance is essential to ensure the long-lasting use and optimal performance of molds. Regular maintenance helps to avoid failures, reduce downtime, and ensure stable product quality. Here are the methods for performing mold maintenance:
Cleaning the Mold:
After each production cycle, clean the mold to remove plastic residues, dust, and other impurities. Use soft brushes and cleaning agents suitable for the mold material to avoid damaging the mold.
Inspecting the Mold:
Regularly check for signs of wear, cracks, or other damage. Focus on areas like the mold cavity, core, cooling channels, ejector pins, and slides.
Pay attention to any signs of rust or corrosion, especially in the cooling channel area.
Lubrication:
Lubricate moving parts such as slides, ejector pins, and cams to prevent wear and ensure smooth movement of components. Use lubricants recommended by the mold manufacturer to avoid mold damage caused by improper lubricants.
Cooling System Maintenance:
Regularly check and clean the cooling system to prevent blockages and ensure proper temperature control. Clogged or dirty cooling channels can lead to uneven cooling and mold defects.
Ensure the flow of cooling water or cooling fluid is normal.
Ejection System Maintenance:
Check the smooth operation of ejector pins and the ejection system. Misaligned or worn ejector pins can affect mold performance and may cause defects in molded parts.
Surface Protection:
Apply protective coatings to the mold surface to prevent rust and corrosion, especially when the mold is exposed to moisture or corrosive materials.
Storage and Handling:
When not in use, store molds in a dry, clean environment to prevent exposure to moisture and contaminants that may cause corrosion and degradation.
Handle molds carefully during transportation to avoid mechanical damage.
