注塑成型的尺寸不仅要满足使用和安装的要求，还要考虑模具制造、设备性能和原材料的流动。严格控制影响注塑件精度的因素，包括模具制造精度、塑料成分和工艺条件。下面济南注塑加工人员为您讲解更多要满足的要求。

The size of injection molding should not only meet the requirements of use and installation, but also consider mold manufacturing, equipment performance and raw material flow. Strictly control the factors affecting the precision of injection parts, including mold manufacturing precision, plastic composition and process conditions. Next, Jinan injection molding personnel will explain more requirements to you.

注塑成型的表面粗糙度是由模具表面的粗糙度决定的，所以模具的表面粗糙度比制品的表面粗糙度低一级，通过打磨抛光达到要求。模腔内注塑件的冷却收缩使注塑件的取出困难。因此，为了便于脱模，在平行于脱模方向的内外表面上应考虑足够的脱模斜度。

The surface roughness of injection molding is determined by the surface roughness of the mold, so the surface roughness of the mold is one level lower than the surface roughness of the product, which can be achieved by grinding and polishing. The cooling shrinkage of the injection molded parts in the mold cavity makes it difficult to take out the injection molded parts. Therefore, in order to facilitate demoulding, sufficient demoulding slope shall be considered on the inner and outer surfaces parallel to the demoulding direction.

注塑成型是注塑模具的成型方法。注塑成型的优点是生产速度快、效率高、自动化操作、颜色多样、尺寸由大变小、产品尺寸容易改变、形状复杂。在复杂形状的大批量生产中，经常使用零件和注塑成型。

Injection molding is the molding method of injection mold. The advantages of injection molding are fast production speed, high efficiency, automatic operation, diverse colors, size changing from large to small, easy to change product size and complex shape. In the mass production of complex shapes, parts and injection molding are often used.

注塑成型是一个技术和实践能力很强的行业。在注塑成型过程中使用塑料原料、碳粉、喷嘴、模具、注塑机、周边设备、夹具、喷雾器、各种辅助材料和包装材料。这些都给注塑车间的管理带来了巨大的成就。与其他行业或部门相比，注塑车间的各级管理人员都存在一定的困难和更高的要求。

Injection molding is an industry with strong technical and practical ability. In the injection molding process, plastic raw materials, carbon powder, nozzles, molds, injection molding machines, peripheral equipment, fixtures, spray, various auxiliary materials and packaging materials are used. All these have brought great achievements to the management of injection molding workshop. Compared with other industries or departments, managers at all levels in the injection molding workshop have certain difficulties and higher requirements.

虽然模具的结构可能会因塑料的种类和性能、塑料制品的形状和结构以及注塑机的类型而有所不同，但基本结构是相同的。模具主要由浇注系统、温控系统、成型件和结构件组成。浇注系统和模具与塑料直接接触，并且因塑料而异。它们是模具中比较复杂和多变的零件，需要高精度的零件。

Although the structure of the mold may be different depending on the type and performance of plastic, the shape and structure of plastic products, and the type of injection molding machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature control system, molding parts and structural parts. The gating system and mold are in direct contact with the plastic and vary from plastic to plastic. They are relatively complex and changeable parts in the mold, requiring high-precision parts.

此外注塑车间的工种和分工繁多，不同的岗位对技能的要求也不同。为了使注塑车间的生产经营顺利进行，需要对各个环节所涉及的人员、材料、设备和工具进行管理。关注我们网站http://www.sdlqmj.com，了解更多相关住注塑加工事项！
