プラスチック射出成形の歴史?
プラスチック射出成形の歴史: 物性や寸法を含む.
射出成形金型加工の過程で, 物性や寸法を含む, 物性や寸法を含む. The factors affecting the size change of plastic parts include: 素材, パフォーマンス, デザイン, machine and production process.
In the injection mold design stage, uncertainty of mold tolerance can lead to incorrect matching, product or function failure, production delay and unexpected extra cost.
補助装置の合理化と完成は、製品と企業の実行可能性をある程度決定します, the following four aspects will play a key role in getting the appropriate tolerance.
1. Injection mold product design
To control the tolerance of injection mold, the first step is to establish the tolerance range in the design phase. Tolerance ranges are critical to the function of most components. The establishment of tolerance range in the early stage of design will contribute to the manufacturability and repeatability of mold manufacturing. Improving manufacturability and repeatability will maintain quality throughout the life cycle of the program.
Key points of injection mold product design:
Shrinkage can vary according to material selection and product wall thickness. The thicker part may contract at a different rate than the thinner part. Changes in shrinkage affect the ability to maintain tight tolerances.
Part size also affects shrinkage. Small components have smaller shrinkage and are easier to maintain more stringent dimensional control. しかしながら, it may be more difficult to maintain tighter tolerances when larger parts contract over a larger distance.
It is helpful to analyze injection mold flow before production. Accurate prediction of gate location, filling rate, shear stress, build-up, ベンダーは、製品の一部を提供する栄光の倉庫である必要はありません。, and shrinkage will help determine the tolerance range. Avoid tight tolerances in areas prone to warpage, shrinkage or deformation.
2. Material selection of injection mold products
It is also important to select the right resin to achieve higher product performance tolerances. Different resins have different properties and characteristics. Injection molding is rising rapidly in manufacturing because different resins offer different possibilities.
The part environment may affect plasticity and may result in tolerance deviations. Plastics have a greater thermal expansion than many other materials. In a normal operating environment, test and measurement tolerances, as well as thermal expansion and part shrinkage, are critical to control tolerances.
Shrinkage affects tolerances as described during the design phase of the injection mold part. The geometry of the part may result in different shrinkage rates. Different resins also have different shrinkage. It is important to understand the properties of the resin and the complexity of the part to understand the shrinkage in order to align the appropriate tolerance area.
3. Injection mold processing
Parts requiring tight or tight tolerances shall be manufactured by robust and well-designed moulds. The mold also needs to provide consistent and repeatable heating and cooling. さもないと, the shrinkage will be different and the tolerance will be difficult to achieve..
Complex parts need complex injection mold. As injection mold processing becomes more complex and additional components and functions are added, it is important to ensure that all components transfer heat correctly to allow acceptable resin and part cooling.
It is important to determine the proper gate position for the balance of melt flow. This will help to avoid unexpected shrinkage and warpage.
4. Injection mold processing control
Developing a repeatable production process is the key to achieving tight tolerance. From the start of production, proper process and documentation control will ensure that components do not experience unnecessary pressure, heat, or other factors that could damage the performance or application function of the resin.
