The Production Process and Time of Injection Molds

The production process and time of injection molds can be summarized in detail as follows:

1,Injection mold manufacturing process

1-1. Product design and evaluation

Mold designers conduct detailed understanding and evaluation of products, including product structure, dimensions, parameters, and other information.

Evaluate whether the existing mold structure can achieve mass production, and proceed to the next step after confirming its correctness.

1-2. Mold design

Based on the evaluation results, design 3D engineering drawings, component drawings, parting drawings, assembly drawings, EDM drawings, etc.

During the design process, it is necessary to consider the structure of the mold, parting surface, pouring system, cooling system, etc.

1-3. Drawing confirmation and material reservation

After the mold master communicates with the designer to confirm that the drawings are correct, the mold materials are reserved.

After the materials arrive, check whether they are qualified and meet the manufacturing and processing requirements.

1-4. Mold processing

Machinist processing: including milling, planing, grinding and other processes, to process the shape and cavity of the mold.

Heat treatment: Heat treatment of mold materials to improve hardness and wear resistance.

Electrode processing: making electrodes for subsequent electrical discharge machining.

Wire cutting processing: Using wire cutting machine tools to process fine mold structures.

Precision machining: including electrical discharge machining, CNC milling, grinding, etc., to improve the accuracy and smoothness of molds.

1-5. Assembly and debugging

Pre assembly inspection, cleaning, and rust prevention.

Assemble the various components of the mold together according to the drawings.

Conduct mold testing and debugging to ensure that the product meets the design requirements.

1-6. Mold acceptance and delivery

Mold acceptance: Check the accuracy, stability, durability and other indicators of the mold.

Deliver to customers and provide necessary technical support and after-sales service.

2,Injection mold production time

The production time of injection molds varies depending on the size and complexity of the product, typically ranging from 15 to 20 days. For simpler molds, the production time may be shorter; For complex and high-precision molds, the production time may be longer. Here are some factors that affect mold making time:

Product structure: The more complex the structure, the greater the processing difficulty, and the longer the production time.

Product size: The larger the size, the longer the processing cycle of the mold.

Product requirements, such as precision requirements, appearance requirements, etc., will affect the production time of the mold.

Material properties: Different materials have different processing properties, which can also affect the production time of molds.

Quantity of molds: If the customer requires multiple sets of molds, the production time will also increase accordingly.
