Plastic mold production process of Hanoi Mould Company

Plastic molding is currently a widely used tool in manufacturing. To create a set of high-quality, stable, and durable plastic molds, the plastic mold production process must comply with strict procedures. In this article, Hanoi Mould and Model will share the plastic mold production process, providing readers with a basic understanding of mold fabrication.

Step 1: Product/Blueprint Research

Upon receiving an order, Hanoi Mold and Model will research the received product/blueprint. To create the mold, we first need to gather all relevant information, which the customer typically provides. We will provide technical advice to help customers achieve the best possible product. According to the plastic mold production process, we need to know the following input information:

  • Product material
  • Product weight
  • Type of mold: 2-plate mold or 3-plate mold
  • Number of mold cavities
  • Cold runner or hot runner system
  • Injection gate type: Point gate, sub-gate, edge gate, etc.
  • Mold core material
  • Mold cavity material
  • Production output
  • Any other relevant information

These details are crucial for mold manufacturing, as they ensure the final product meets the desired specifications. By understanding the product requirements, we can proceed to the next steps of mold production with precision and accuracy.

Step 2: Mold Design – Plastic Mold Production Process

After studying the product/blueprint and gathering the necessary information, the design engineers at Hanoi Mold and Model will propose and design the mold. This is a crucial step in the plastic mold production process. It determines the optimal outcome of the product and guides the mold manufacturing process, ensuring accuracy.

Hanoi Mold and Model company possesses a skilled and professional design team. After adding the layout and proposal, the design department will proceed with designing and creating CAD/CAM machining data. Following strict plastic mold production procedures, our design engineers meticulously and thoroughly carry out each step, including separating the mold into components, processing the mold core, creating assembly drawings, creating detailed drawings, designing and fabricating EDM electrode drawings, checking the drawings, and releasing the drawings.

Once the 3D drawings are finalized, the design team collaborates with other departments to conduct a comprehensive evaluation of the design. It is necessary to study whether the drawings meet the customer’s requirements, and feasibility with the existing machinery and equipment at the factory, and make any necessary adjustments to ensure the best fit and optimization.

Step 3: Mold Machining and Fabrication

In the plastic mold production process, this stage requires the use of high-precision machinery and equipment to perform:

  • Machining surfaces, details, mold cavities, etc., using precision machining tools such as milling machines, grinders, lathes, drills, etc.
  • Post-machining polishing: Polishing and smoothing the machining marks. Inspecting and treating vents, dulling or chamfering edges where applicable, and ensuring cleanliness. The surface quality of the plastic product depends entirely on the mold cavity’s smoothness, so this process is carried out meticulously and accurately. We perform the polishing process in two stages: preliminary polishing before assembly and meticulous polishing after assembly.

Step 4: Assembly and Inspection

This is the final step to complete the plastic mold production process. After all the mold components and parts are completed, they are assembled. Before assembly, we inspect the components in terms of quantity and specifications to ensure that all of them meet the required standards accurately.

The assembly process requires a high level of accuracy to ensure that when put into operation, the mold will generate efficient products. The mold plates, cores, bases, and mold shells will be assembled into a complete mold set.

Step 5: Mold Testing

To ensure the proper functioning of the mold and meet the initial requirements of the customer, the mold will undergo a trial operation after the completion of assembly. The plastic mold production process will be considered complete if the trial-produced products meet the requirements. Any detected errors will be rectified before delivering the mold to the customer.

Step 6: Delivery of Plastic Mold to the Customer

Hanoi Mold and Model company follows a professional plastic mold production process. We guarantee that our plastic molds meet the required quality standards and are delivered on time according to the agreed contract timeline.

Above is the plastic mold production process at Hanoi Mold and Model Company. We hope this information is helpful to you.
