            塑料模具的熱處理方式有哪些?

            來源:http://www.environmentandpeople.net/ 日期:2021-03-09 發布人:admin


            隨著我國塑料產業的快速發展,塑料制品已經廣泛應用于我們生活的方方而面,如商品包裝、建筑材料,汽車配件等等。近年來,精密塑料制品的需求不斷增大,市場潛力十分巨大。
            With the rapid development of China's plastic industry, plastic products have been widely used in all aspects of our lives, such as commodity packaging, building materials, auto parts and so on. In recent years, the demand for precision plastic products is increasing, and the market potential is huge.
            相應地,我國塑料模具的市場也不斷擴大,對于模具制作工藝的要求也不斷增加。熱處理工藝是塑料模具制作中的關鍵環節,與塑料模具的生產質量和使用性能密切相關。
            Accordingly, China's plastic mold market is also expanding, and the requirements for mold manufacturing process are also increasing. Heat treatment process is a key link in the production of plastic mold, which is closely related to the production quality and performance of plastic mold.
            1、塑料模具的精度
            1. Precision of plastic mould
            熱處理過程中產生的變形是導致塑料模具精度降低的主要問題。具體來說,在模具熱處理時,由于各個面的加熱速度和冷卻速度不同,使各個面出現溫度差。導致模具出現體積膨脹不均勻的現象。引發模具組織轉變不均勻。因此產生組織應力和熱應力。當熱處理中產生的殘余應力大小超過模具的承受范圍時,就會導致模具發生變形,使模具精度降低、甚至失效。
            The deformation in the process of heat treatment is the main problem that leads to the decrease of plastic mold precision. Specifically, in the mold heat treatment, due to the different heating speed and cooling speed of each surface, the temperature difference of each surface appears. It leads to the uneven expansion of the mold. The results show that the microstructure transformation is uneven. Therefore, there are structural stress and thermal stress. When the residual stress produced in heat treatment exceeds the bearing range of the die, the die will be deformed, and the accuracy of the die will be reduced or even fail.
            2、塑料模具的強度
            2. Strength of plastic mould
            塑料模具的熱處理工藝是決定其強度大小的重要因素。具體來說,當熱處理工藝的選擇不合理,熱處理過程的操作不規范,或是熱處理設備存在散障時,都會降低塑料模具的強度,導致生產的模具不合格。因此,廠家在生產塑料模具時,必須按照模具的不同強度要求,根據不同的模具用材,采用相應的熱處理工藝。
            The heat treatment process of plastic mold is an important factor to determine its strength. Specifically, when the selection of heat treatment process is not reasonable, the operation of heat treatment process is not standardized, or there are scattered obstacles in heat treatment equipment, the strength of plastic mold will be reduced, resulting in unqualified production mold. Therefore, when producing plastic mold, the manufacturer must adopt the corresponding heat treatment process according to the different strength requirements of the mold and the different mold materials.
            3、塑料模具的使用壽命
            3. Service life of plastic mould
            塑料模具的熱處理工藝也是決定其使用壽命的關鍵因素。具體來說,當熱處理工藝的選擇不合理或操作不規范時,會引發模具在熱處理過程中產生組織結構不合理和晶粒度超標等問題,使得塑料模具的韌性下降,抗冷熱疲勞性降低,抗磨損性變差,導致模具的整體性能降低,影響模具的使用壽命。
            The heat treatment process of plastic mold is also the key factor to determine its service life. Specifically, when the selection of heat treatment process is unreasonable or the operation is not standardized, it will lead to the problems of unreasonable structure and excessive grain size in the process of heat treatment, which will reduce the toughness of the plastic mold, reduce the cold and hot fatigue resistance and wear resistance, reduce the overall performance of the mold and affect the service life of the mold.
            4、塑料模具的制作成本
            4. Production cost of plastic mould
            塑料模具的生產成本與熱處理工藝密切相關。具體來說,當模具采用了不恰當的熱處理工藝或操作不規范時,會導致模具的耐磨性、耐腐蝕性、抗冷熱性,韌性,硬度和強度等性能降低,甚至導致模具出現變形、失效。因此,采用合理的熱處理工藝能夠提高塑料模具的生產質量,從而降低模具的生產成本,提高生產廠家的經濟效益。
            The production cost of plastic mold is closely related to the heat treatment process. Specifically, when the mold adopts the improper heat treatment process or the operation is not standardized, the wear resistance, corrosion resistance, cold and hot resistance, toughness, hardness and strength of the mold will be reduced, and even lead to the deformation and failure of the mold. Therefore, the reasonable heat treatment process can improve the production quality of plastic mold, reduce the production cost of mold, and improve the economic benefits of manufacturers.
