过度与插入成型

In the current industrial field, multi-material injection molding finds wide applications in producing products that meet multiple functions and aesthetic purposes. Explicitly speaking, the multi-material injection molding mainly comes in two forms, namely the Overmolding VS Insert Molding.
由于这两种成型技术具有一些相似之处，而也存在一些关键差异。因此，您可以在选择之前学习有关插入成型和过度插入的相关信息是有远见的。
Today, this is a piece of good news. This guide explains Overmolding VS Insert Molding in terms of definition and differences covering benefits, applications. It will help you more easily identify which type of injection molding technologies is apt for your needs.

如果您要在两种成型技术上浏览Wikipedia页面，您会发现它们冗长且难以理解。因此，为了更好地理解它们，让我们在下面的详细说明：

插入成型是一个过程，在该过程中，要将插入物预先放入模具中，以使注射塑料流动。这些插入物有各种类型，例如金属和不同种类的塑料。这种注射成型技术的果实是一块围绕整个插入物的模制塑料。这种塑料通常比以二级装配方式产生的塑料更固体和耐用。

Most commonly, overmolding is a process in which a single component or product takes into shape by collectively using two or more different materials.
In such a process of molding technology, there typically exists a first material ( aka substrate ). This part is rigid and will be partially or wholly covered by the TPE ( aka overmold materials ) or other materials.

The benefit of insert molding are evident across a variety of industries. It finds wide applications in miscellaneous industries ranging from automobiles, electrical parts or components, medical instruments and devices, consumer products.

Cost-effective:

The insert molding serves as a low-cost method to decrease the part size and weight and to produce strong, durable, and reliable finished products.

更好的产品设计：

The insert molding can boost component reliability, increase the strength of each component. All products produced in this technology features corrosion-resistant, strong, durable, and reliable.

减少集会时间和人工成本：

在插入成型的过程中，将插入物插入模具的步骤可以使用某种形式的自动化来实现。这节省了技术人员的时间和精力，因此他们可以致力于更复杂和重要的事件。

In contrast, the overmolding boasts some outstanding benefits alike the insert molding as follows:

更好的产品性能：

热塑性弹性体（又名TPE）是一种共聚物或由具有热塑性和弹性特征的材料组成的聚合物的物理混合物。作为理想的材料，独特的弹性性能使TPE成为保护产品并通过减少冲击，振动和噪音延长其保质期的自然障碍。

Better Product Appealing:

The TPE comes in various colors and texture and can act as a visually attractive veneer. Moreover, the transparent TPE surface can be printed with an exclusive logo, advertisements, or instructions.

较低的产品成本：

过度过度是有效的，因为它在几个方面增强了产品性能。因此，它可以在一定程度上降低生产成本。

All these molding technologies have benefits that are conducive to help cut your project budget. Meanwhile, the quality of your products will not suffer loss. These two injection molding technologies have their respective uniqueness.

插入成型可能有助于添加徽标，广告。这样，整个制造成本将大大减少。同时，过量的可能有利于将零件放在一起。

If you want to satisfy your targeted customers, you can use these two methods singly or collectively according to circumstances. Besides, you should also take the external environment and the concrete needs into consideration to determine which type of methods is more suitable.

过量技术中使用的材料取决于兼容性，附着力和其他因素，例如材料过度材料的厚度，材料本身的柔软度等。

1. HDPE.

部高密度聚乙烯(HDPE)或polyethylene is a thermoplastic polymer produced from the monomer ethylene. Such materials feature a high strength-to-density ratio and recyclable property. HDPE is widely applicable in the production of plastic bottles, geomembranes, plastic lumber, and so on.

2. PMMA（丙烯酸）

甲基丙烯酸甲酯（又称PMMA）是一种透明的热塑性，通常以薄板形式使用。它可以作为替代轻质或耐碎玻璃的物质。

3. POM

聚氧甲基（又名POM）是一种工程热塑性塑料，适用于需要高刚度，低摩擦和出色尺寸稳定性的精确组件。

POM features a high strength, hardness and rigidity under −40 °C. Although it is opaque white intrinsically, it can come into being in any colors.

It is popular in the automotive and consumer electronics industry, such as small gear wheels, ball bearings, ski bindings, fasteners, guns, knife handles, etc.

The materials used in insert molding technology depend on the mold and other elements, such as the wall thickness of the shaped product.

The main focus relies on the sustainable running of the machine in the course of molding.

1. 热塑性塑料：

这样的材料对化学物质具有生态友好性和耐药性。以下是市场上热塑性材料的主要种类：

一个。Polyethylene.

b。Polystyrene.

C。尼龙。

2.Thermosets:

Thermosets are much similar to thermoplastics. But they are not eco-friendly, because they can not be used for many times.

以下是市场上热销材料的主要类型：

一个。酚类。

b。环氧树脂。

3.弹性体：

Such materials are elastic and recyclable.

它们是非常环保的材料，非常适合家用电器和汽车产品制造。

一个。Natural Rubber.

b。聚氨酯。

过度销售在多个行业中发现了广泛的应用。过度燃料不仅适用于大量私人产品，例如牙刷，而且还适用于许多高价值产品，例如塑料发动机组件。当它在医院使用时，它可以使产品更稳定，清洁和防潮。当它在汽车行业中使用时，它可以放弃进行额外的组装步骤，这些步骤需要使用粘合剂。

The following are the concrete applicable fields:

• 塑料或金属组件配有软握把手柄。
• Medical appliances.
• 设备旋钮。
• Automotive components.
• 封装电子设备。
• 电气部件。
• Controls.

The insert molding finds a wide applications in the various industries.
注塑技术是最好的设计ing smaller products. The products in small sizes often find a place in commercial uses that require additive manufacturing and laser sintering.

It is also popular in developing compact products. In contrast, the products in the overmolding way are much larger. Therefore, Overmolding takes a much longer time to produce a product.

The following are some concrete applications:

• 汽车行业。
• Consumer goods.
• 医疗行业。
• 电子产品。
• Aerospace.
• 管阀。
• Controls.
• 电气组件。
