PRODUCTION OF LARGE-SIZED PLASTIC INJECTION MOLD IN VIETNAM

Large-sized mold and plastic injection mold manufacturing is one of the crucial industries in the manufacturing and fabrication sector. Mold manufacturing is an indispensable stage in creating the outer mold layer, facilitating rapid production, producing many products, and maintaining consistent size and shape.

Today, Vietnam is emerging as a leading plastic injection mold manufacturing hub in the region, especially in the field of large-sized plastic injection mold production. With abundant human resources, competitive production costs, and technological advancements, Vietnamese businesses increasingly assert their position in the international market.

At Hanoi Mould, we possess the skills, experience, and capabilities to create large-sized plastic injection molds for various industries. Here are some images of large-sized plastic injection molds at Hanoi Mould:

Hanoi Mould Technology Co., Ltd.’s Plastic Injection Mold Manufacturing Process:

To create a high-quality plastic injection mold with stability and long lifespan, the mold manufacturing process must adhere to a rigorous procedure:

Step 1: Product/Drawing Analysis

Upon receiving an order, Hanoi Mould will conduct a thorough analysis of the provided product/drawing. To successfully manufacture a mold, especially large-sized plastic injection molds, we need complete relevant information. This information will be provided by the client. We will offer technical advice to ensure the client receives the most perfect product. Our plastic mold manufacturing process requires the following input information:

• Product material
• Product weight
• Mold type selection: 2-plate or 3-plate mold
• Number of mold cavities
• Hot or cold runner system (Cold runner, hot runner)
• Injection gate type: Point gate, sub-gate, edge gate…
• Cavity material
• Mold base material
• Injection volume
• Other relevant information

Step 2. Mold design – Plastic mold manufacturing process

After analyzing the product/drawing and acquiring necessary product information, Hanoi Mould’s design engineers will develop a plan and design the mold. This is a crucial step in the plastic mold manufacturing process. This stage determines product optimization. It outlines a clear path for mold production, ensuring accuracy.

Hanoi Mould boasts a team of skilled and professional designers. After adding the layout and explaining the plan, the design department will proceed with designing and generating CAD/CAM machining data. With our rigorous plastic mold manufacturing process, our design engineers meticulously and thoroughly execute all stages, including:

• Separating the mold into components
• Processing the mold core
• Creating assembly drawings
• Creating detailed drawings
• Designing and manufacturing EDM electrode drawings
• Checking drawings
• Issuing drawings

Once the 3D drawing is finalized, the design team will collaborate with other departments for a comprehensive design evaluation. It’s essential to assess whether the drawing meets the client’s requirements, if it’s feasible with the factory’s existing machinery, etc., to make necessary adjustments for optimal results.

Step 3: Mold Machining and Fabrication

In the large-sized plastic injection mold manufacturing process, this stage requires high-precision machinery and equipment to perform the following:

• Machining surfaces, details, and cavities on precision machining equipment such as milling machines, grinding machines, lathes, and drilling machines.
• Post-machining polishing: Polishing and smoothing machining marks. Inspecting and processing burrs, rounding or chamfering permissible areas, and thorough cleaning. The quality of the plastic product surface depends entirely on the mold cavity’s polish, so this process is always performed meticulously and accurately. We always perform polishing in two stages: rough polishing before assembly and thorough polishing after assembly.

Step 4: Assembly and Inspection

This is the final step in completing the plastic mold manufacturing process. After the mold components and parts are finished, assembly will take place. Before assembly, we will inspect the parts according to quantity and specifications to ensure they all meet the required accuracy.

The assembly process demands high precision to ensure the mold produces efficient products when in operation. The mold plates, cores, bases, and mold bodies will be assembled into a complete mold unit.

Step 5: Mold Trial Run

To ensure the mold functions properly and meets the client’s initial requirements, the mold will undergo a trial run after the assembly is complete. The plastic injection mold manufacturing process is considered finished if the trial-run product meets the requirements. Any errors will be corrected before delivery to the client.

Step 6: Delivery of the Plastic Injection Mold to the Client

Hanoi Mould has a professional plastic mold and large-sized plastic injection mold manufacturing process. We guarantee that our large-sized plastic injection molds meet quality requirements and are delivered on time, as per the contract agreement.
