Mold Industry production knowledge

The company is a mold company. In compliance with the protection of intellectual property rights (IP), I would like to summarize some of the current knowledge in this industry.

1. Mold Classification
The design of the mold can be divided into soft mold and hard mold. The life cycle of a soft model is short. It is often an experimental design. It is used to check whether the product design is reasonable. A hard model is generally designed for a sold product and its life cycle is long.
According to the structure, it can be divided into two-plate (2-plate) and three-plate (3-plate). As for what kind of product needs to be designed into three-plate, the designer needs to according to the product characteristics, comprehensive Judgment.

2. tooling life)
After the mold production is completed, you need to generate products on the injection molding machine. The injection molding machine has a high pressure to take the raw materials like liquid into the product. When the mold is under high pressure, the long-term force may cause deformation, and the size after deformation does not conform to the specifications, so it needs to be decommissioned and cannot be used for production products. Therefore, the steel mold is placed in the warehouse and can be preserved for decades when it does not change with the material in the air. However, when it is used to produce products, the life cycle is often determined based on the number of inject injections it can accept. When the mold is deformed due to pressure, it cannot be used any more.
In professional terms, shots is used. For example, 10 K shots can be injected 10 thousand times to form a product. 15 K shots can be injected 10 thousand times.

3 Hot Runner System
There is a very important component in the mold: Hot Runner System ). at present, there are only a few companies in the world that can produce this product. The role of Hot Runner is to prevent plastic solidification in the mold and the product cannot be formed. In a metaphor, we use water pipes to bring water from one place to another, which requires a strong effect and water itself will not flow, you need to use external power to push the water to another place.
Hot Runner occupies a considerable proportion in the cost of the mold. Generally, Hot Runner systems are enough when the mold starts production.
I know the companies that produce Hot Runner systems include Eden, hasco, husky, moshould master, yudo.
In the quotation software I developed, the price of Hot Runner is based on the weight of the die embryo. Different types of Hot Runner are used to export the price directly.

4. mold structure
DoProgramFor many years, "=" is the most widely used symbol. It initializes the variable value, assigns the value of one variable to another, and then calculates the result. First, you will understand the general relationship.
Insert = cavity + core product = front mode + back mode (also known as public mode and master mode)
Sometimes there is a sub insert. The formula should be like this.
Insert = cavity + core + sub-insert
Moshould base = a plate + B plate + Sb + (TCP + BCP) + (ST + SP) + (EP + ERP)
The formula is short for it. It doesn't matter if you don't understand it. When you make software about this structure one day, you can see this formula as if you saw baby, it took me a few days to get familiar with this relationship.
Special Feature = slider + lifter + Ejector System
Sorry, because the company is used to describe products in English, I don't know what their exact Chinese saying is.
The above three formulas roughly show the components of a mold.
Three major components: insert, mowould base, special feature.
Each part is made up of smaller parts. Hot Runner needs to be purchased and installed directly from the manufacturer.
Usually, you only need to pay attention to how your part can be efficiently produced and whether it is reasonable. If you want to make a quotation software, you must have a deep understanding of the relationship between these parts.

5. Mould Material
It is usually steel, and some unimportant parts can be iron. Common materials include 718 H, 738 H, and. When designing a product, the customer usually specifies which material to use. Swiss Army knife and German Double stand in the world are very popular, Swiss Army Knife steel is usually used with rust-proof Special Steel, after 1040 degrees Celsius heat treatment, the hardness of the knife is rc56.

6. How is the product produced?
You will understand the chart directly.

The product was launched. It may be a mobile phone shell, but you know it is a product.

7. Mold Production Process
Creating a mold is not a pipeline operation. It is indirect to track whether the production process is executed according to schedule.
With the company's current scheme (PCD tracker), place the bar code on the key part, and start and complete the entry into a production workshop (in & out ), scan the specified Machine to track the production status of the part.
Because it is not an assembly line, the company's system can allow Custom production lines, first establish n workshops, according to the characteristics of different mold Products, the production control department determines his production sequence, adds a bar code, and starts production in the workshop. Each place, the incoming and outgoing data is scanned. The incoming data indicates that the production of this part starts, and the outgoing data indicates that the production is completed, to track the production progress.

I met the production tracing solution for pipeline jobs, using RFID technology. Before production, each part is labeled with an RFID tag, which is equivalent to issuing an ID card to the part. The part can be identified by reading the RFID card on the part. Along with this part going to a workshop, you should take the initiative to contact the part on the specified machine, and the system will record the workshop in which the part is currently in progress to track the production progress.
There is also the computer motherboard manufacturing industry, which is also a pipeline operation. The difference is that starting from the very beginning, it is a piece of copper. After countless chemical and physical changes, the main board is finally produced. You have no idea which copper is used for production. Some unqualified materials are often decommissioned during the production process. I never understand their production tracking scheme, but I know that they control the inventory, WIP, and raw materials quite well, and the quality in the production process is also well controlled to reduce waste.
The previous company was a provider of solutions for the garment industry in Asia No. 1, and another supplier with 17% of the world's computer boards.
Each solution has opponents and supporters who need software and hardware support. Their solution may not be the best, but they have done it. They did it. because they are all super companies in the world.

As a result, I think that some of my previous companies are holding meetings every day to discuss and study issues, that is, they are not steadfast enough to implement the solutions. Today, I just designed a solution and changed it in two days.
I used remoting for a while. After hearing the ad of WCF, I started to use WCF. I used nhib.pdf to complete more than half of the system and started to use application block. Then I simply didn't control it, each person has a set of data access solutions. After a while, the configuration will be put into the database, and all the configurations will be stored in an applicationconfiguration table. Later, I don't know who said the database performance is poor, some programs put the configuration in the XML file, or write the configuration directly more conveniently.CodeLi

8 DFM
DFM is designed for manufacturablity for manufacturing. DFM is used to improve the manufacturing process of products.
The description in English is DFM is the genral Engineering Art of designing products in such a way that they are easy to manufacture.
To this end, I have also developed a DFM System for DFM tracking by the Project Department and the design department. When the design department finds that the product design is unreasonable, it should report to the PE responsible for this project. The PE should contact the customer to inform the customer of the unreasonable and the need for improvement. The customer's design is product-centric, with few manufacturing considerations. if the product is known, it will be unreasonable, and the loss will be too great. Therefore, prior to manufacturing, the design department engineers should examine the product manufacturing feasibility from a variety of conveniences.

9 creation process of mold Products
The process from placing an order by the customer to sending the product to the customer is generally as follows:
Quotation & Po quotation & Order --> Contract Review meeting Review --> mold design and development input requirements design input --> Mold Design and Development Review Report DFM --> Start production, mold Progress follow-up record Manufacturing --> test mode T0, T1 --> walk mode, FOB.
This is also the whole process of producing a new mold product. This process is also suitable for general product development.

For the time being, we have made a lot of research and stick to our original ideas. For more information, see Liangliang. It is applicable to plastic molds. It is not suitable for molds such as gold, aerospace, and automobile tires.
