Häufige Probleme und Vorsichtsmaßnahmen bei der Herstellung von Kunststoffformen

Der Herstellungsprozess eines Satzes von Kunststoffformen ist kein einstufiger Prozess. Es ist notwendig, die strukturelle Gestaltung des Produkts gut zu verstehen, um viele Probleme im nachfolgenden Produktionsprozess zu vermeiden, wie schrumpfen und blinken.
So, what issues should you pay attention to when making molds?

Don’t just focus on product design and neglect mold manufacturing

Some users just focus on product development when developing products or testing new products, always neglect communication with mold maker.
After the plan of product design is initially determined, there are three benefits to contacting the mold manufacturer in advance:

  1. It can ensure that the designed product has a good forming process and will not modify the stereotyped design because the part is difficult to process.2, the mold maker can make design preparation in advance to prevent ignorance in the inconsistency, affecting the construction period.

    3, the production of high-quality molds, only the supply and demand cooperate closely, then can reduce costs and shorten the cycle ultimately.

Don’t just concern the price, we must consider all aspects of quality, cycle time and service:

1. Es gibt viele Arten von Schimmelpilzen, die sich grob in zehn Kategorien einteilen lassen.
According to the different requirements of parts materials, physikalische und chemische Eigenschaften, mechanische Festigkeit, dimensionale Genauigkeit, Oberflächenfinish, Lebensdauer, Wirtschaft, usw., different types of mold forming are selected.

2. The mold with high precision requires the use of high-precision CNC machine tools, and the mold material and forming process have strict requirements. CAD / CAE / CAM mold technology is also needed to design and analyze.

3, some parts have special requirements due to molding, the mold also needs to use hot runner, gas-assisted molding, nitrogen cylinder and other advanced technology.

4, manufacturers should have CNC, EDM, wire cutting machine and CNC copy milling equipment, high-precision grinding machine, high-precision three-coordinate measuring instrument, computer design and related software.
5, the general large-scale stamping dies (such as automotive cover parts mold) should consider whether the machine tool has a crimping mechanism, and even side lubricants, multi-station grade and so on.
In addition to punching tonnage, it is necessary to consider the punching, feeding device, machine tool and mold protection device.

6. The manufacturing methods and processes of the above molds are not available and mastered by every enterprise.
When choosing a collaborative manufacturer, you must understand its processing capabilities, not only look at hardware equipment, but also combine management level, Verarbeitungserfahrung und technische Stärke.

7, for the same set of molds, different manufacturers sometimes have a big gap.
You should not pay more than the cost of the mold, und sollte nicht geringer sein als die Kosten der Form.
Formenhersteller, wie du, have to make a reasonable profit in the business.
Ordering a set of molds with much lower quotations can be a hassle to start.
Users must proceed from their own requirements and comprehensively measure them.

Avoid multi collaboration, try to make mold and product processing in one-stop:

Precautions in the processing of plastic molds:

1. Der Schrumpfungskoeffizient jedes Materials ist unterschiedlich, and the plastic mold should have a reasonable shrinkage rate.

2. The plastic mold should have sufficient rigidity, otherwise it will be deformed when the mold is kept under pressure, causing “flash”.

3. If the product is opened while the mold is being opened, die Auswerferseite der Spritzgießmaschine eingestellt werden (but some injection molding machines do not have this function).

4. Choose a reasonable demoulding method and choose a reasonable position and quantity of the ejector to ensure that the product is not damaged during the ejection process.

5. Die Abkühlung (Wasserdurchgang) in the plastic mold is related to factors such as product size, Form, plastische Eigenschaften, and holding time.

6, plastic mold to choose a reasonable position of the exhaust and its amount of control.
Andernfalls, the plastic is not filled and the product is “Mangel an Material”.

7. The fixing method of the plastic mold and the injection molding machine should be reasonable, and it must be reliable and firm, and prevent accidents caused by the displacement of the mold.
And it is easy to disassemble.

8. The plastic mold moves with the injection molding machine together with the moving part without the return spring. It is the mold ejector plate and the machine ejector pin (commonly known as the strong top).

9. The injection channel should be selected reasonably so that the material can reach every place evenly (the flow path is equal), and there must be sufficient storage to ensure that the plastic is replenished during the shrinking process.

10. Post-treatment of plastic mold materials is not required because: plastic is soft, no special requirements such as hardness are required, and the heat treatment process may cause deformation of the mold.

11. The roughness level of the plastic mold cavity should reach the “mirror level”, otherwise the product should be demoulded, and the product should be too strong to cause product damage when the product is ejected.
The roughness of the locating pin, the clamping surface and other parts are standard.

Zusammenfassend, in the process of making the mold, the design of the product cannot be emphasized, and the production of the mold is neglected.
Once the mold appears any problems, it will directly affect the injection molding of the product, which directly affects the quality and delays the delivery time of the product.
Deshalb, in the early stage of making plastic molds, the customer and the factory engineers should better communicate the products in order to achieve the best mold manufacturing.
