In the mold design process, steps such as proofreading, drawing review, drawing tracking and printing are crucial. The purpose of these steps is to ensure the accuracy and completeness of the mold design documentation.
First, proofreading is an essential step. During this process, designers need to carefully check everything in the mold design document, including size, shape, material and other relevant parameters. Through proofreading, any possible errors or omissions can be found and corrected to ensure the accuracy of the design.
Secondly, drawing review is also an important link. During this process, designers need to carefully review the mold design drawings to ensure that they comply with relevant standards and specifications. This includes checking aspects such as drawing proportions, dimensions, symbols and annotations. Through drawing review, you can ensure that the design meets the requirements and can be smoothly translated into the actual manufacturing process.
Next, drawing tracing is also a critical step. During this process, designers need to track drawing versions of the mold design and record all modifications and updates. This helps keep design documents consistent and allows changes to be traced from version to version. Through drawing tracking, you can ensure that the design document is always consistent with the latest version and can reflect any possible modifications in a timely manner.
Finally, printing is the final step in the mold design process. During this process, designers need to print out design documents to facilitate communication with team members, customers, or other relevant personnel. Printed design documents can provide more intuitive visual effects and can help people better understand and evaluate the accuracy and completeness of the design.
To sum up, steps such as proofreading, drawing review, drawing tracking and printing play a vital role in the mold design process. Through these steps, the accuracy and completeness of mold design documents can be ensured, thereby improving the quality and efficiency of the design. Below is an outline of the typical process:
- Proofreading:
- After completing the mold design, the first step is proofreading the entire set of drawings, including part drawings, mold component drawings, and assembly drawings.
- Proofreading involves carefully checking for spelling errors, grammatical mistakes, and numerical inaccuracies in the dimensions and annotations.
- Verify that all the information in the drawings aligns with the design specifications and meets the requirements of the intended mold.
- Drawing Review:
- Once the proofreading is complete, the mold design team conducts a comprehensive drawing review.
- The drawing review involves multiple team members, including mold designers, engineers, and project managers, to ensure a thorough examination of the design.
- During the review, team members check for design errors, dimensional accuracy, and adherence to design standards and specifications.
- Any necessary modifications or improvements are identified and documented for implementation.
- Drawing Tracing:
- After completing the proofreading and drawing review, the finalized mold design drawings are traced or updated in the computer-aided design (CAD) software.
- The mold designers incorporate any changes or improvements identified during the review process into the CAD model of the mold.
- Drawing tracing ensures that the final design accurately reflects the reviewed and approved version.
- Printing of Mold Design:
- Once the drawing tracing is complete and the mold design is ready for production, the final step is printing the mold design documentation.
- The mold design package typically includes part drawings, assembly drawings, and detailed drawings of individual mold components.
- High-quality printing is essential to create clear and precise drawings for use during the mold manufacturing process.
- Depending on the complexity of the mold and the number of drawings, large format printers may be used to accommodate the size of the drawings.
- Document Control:
- Throughout the entire process, proper document control is essential to keep track of revisions, updates, and approvals.
- Each version of the mold design is typically assigned a unique version number and documented in a revision history log.
- All team members involved in the mold design process should have access to the most current and accurate version of the mold design documentation.
By following a systematic approach to proofreading, drawing review, drawing tracing, and printing, the mold design team ensures that the mold design documentation is error-free, meets all specifications, and serves as a reliable reference for the successful fabrication of the mold.
Proofreading, reviewing, tracing and printing
(1) Relationship between mould and its parts and plastic part drawings
Whether the material, hardness, dimensional accuracy and structure of the mold and mold parts meet the requirements of the plastic part drawing.
(2) Plastic parts
Whether the flow, shrinkage cavity, weld line, crack, and demoulding slope of plastic material flow affect the requirements for the use performance, dimensional accuracy, surface quality, etc. of plastic parts. Whether the pattern design is insufficient, whether the processing is simple, and whether the shrinkage of the molding material is selected correctly.
(3) Molding equipment
Whether the injection volume, injection pressure and clamping force are enough, whether there are problems in the mold installation, the south core and demoulding of plastic parts, and whether the nozzle of the injection machine is in correct contact with the mouthpiece.
(4) Mold structure
1) Whether the parting surface position and finish machining accuracy meet the requirements, whether there will be overflow, and whether the plastic parts can be kept at the side of the mold with ejector after opening the mold.
2) Whether the demoulding method is correct, whether the size, position and quantity of the extension rod and push tube are appropriate, whether the push plate will be stuck by the core, and whether the formed parts will be scratched.

Mold design is a critical aspect of the mold processing cycle. To ensure that the mold meets the required specifications, several steps must be taken, including proofreading, drawing review, drawing tracing, and printing. In this article, we will discuss the process of proofreading, drawing review, drawing tracing, and printing in mold design.
The first step in mold design is proofreading the design to ensure that it meets the required specifications. Proofreading involves checking the design for accuracy, ensuring that all dimensions are correct, and verifying that the design meets the customer’s requirements. This process helps identify any errors or issues that may impact the mold’s functionality and ensures that the mold design meets the required quality standards.
Once the design has been proofread, the next step is drawing review. Drawing review involves verifying that the design meets all required safety and regulatory standards, including any applicable industry or government regulations. Drawing review helps ensure that the mold design is safe to use and meets all legal requirements.
The next step is drawing tracing, which involves tracing the design onto a template or a specialized tracing paper. This process allows the mold manufacturer to create an accurate and detailed representation of the mold design, which can then be used to create the mold.
After the drawing has been traced, it is printed onto specialized paper using a high-quality printer. Printing the design onto specialized paper ensures that the design is accurate, clear, and easy to read, which is critical during the mold manufacturing process.
In conclusion, proofreading, drawing review, drawing tracing, and printing are essential steps in the mold design process. These steps help ensure that the mold meets all required specifications, including accuracy, safety, and regulatory compliance. By taking the time to review and verify the mold design, manufacturers can ensure that the mold meets the required quality standards and produces high-quality parts.
