2K注入成型& Co injection molding

2K注射成型也被称为两次注射成型，双射击注射成型，两次射击成型，两个颜色注射成型，双射击注射成型，双射击成型，双注射成型，双注射成型，双射击成型，CO注射成型和BI注射型。成型。2K注射成型过程两种不同的塑料或2种颜色成一个集成部分。这些塑料可以具有不同的结构，颜色，特性和硬度水平。2K注入成型工艺减少了注入成型的设置和组装时间，整合功能，结合了产品属性，并降低了材料和工作步骤。它创建了高质量的连接以及两种具有不同特性的材料的优势。借助CO注入成型工艺，零件可以包括透明的窗户，可移动片段，水上罩，集成的垫片或声音或振动减少。机器，2K注射模具和2K成型材料的配位在2K注射成型中尤其重要。注射单元必须和谐起作用，但必须始终可以独立控制。

除了我们1 k注塑件,Stebro Mold has become well-known for its 2K moulding capability. Our facilities and expertise enable us to produce complicated 2K parts from two different polymers, especially when it comes to complex geometries. We can help you to optimize the 2K plastic part design, select the best materials that meet bonding requirements for 2K mold design, 2K mold manufacturing, and co injection molding manufacturing, all are under one roof.

2K注入模制示例

以下是我们为客户制作的一些CO注射成型项目。要了解2K成型技术是否适合您的项目，请与我们联系，我们的工程师将为您提供出色的2K成型过程。

Two shot injection mouldingPart design

Transitions between wall thickness should be gradual to reduce flow problems, such as back fills and gas traps.
Deep, unventable blind pockets or ribs should be avoided.
长抽取应有每侧3-5°的草稿，以帮助组件弹出。
The TPE thickness should be less than or equal to the thickness of the substrate to prevent warpage; this is especially critical for long, flat geometries.
产品中均匀的壁厚是获得最佳成型周期时间并避免缩小标记的均匀壁厚。壁厚范围从1.5 mm-3 mm不等，可确保在大多数过度过度应用中良好的粘结。如果该零件需要使用厚的TPE截面，则应将其核心以最大程度地减少收缩问题，减少零件的重量并降低周期时间。

Variations of two shot moulding

There are a few variations of two shot moulding, including rotary platen, movable core, and overmold. The first two require a second injection unit, two runner systems, and two processes. The latter, in most cases, involves two separate molds—one for each material—but can also be run with one mold, two runner systems, and pick-and-place part transfer, either manually or with a robot.

2K Mold Manufacturing

To speed up the mold manufacturing process without sacrificing quality, you need the right technology. We use UG to design and manufacture molds. The 2K Mould manufacturing was done toally according to the 3D mold design. For manufacturing the 2K mold, we use different manufacturing machines such as Mikron CNC, AgieCharmiles EDM, Sodick Slow Wire Cut machine, Grinding Machine and Gun Drill Machine. After machining all the components, we have to measure the key size on the CMM machine. It is very important to avoid flash at the parting surface.

2K Injection Mold Trial

我们的2K Engel注射成型机不仅用于2K注射成型生产，而且还适用于2K模具试验。

2K注入成型Manufacturing

We offer the injection molding on state-of-the-art injection molding machine Engel with closing force of 130T and rotating table, we are planning to buy another 260T 2K Engel Injection molding machine in 2020.
我们提供了有关2K技术领域的完整支撑物 - 从内部产品开发，一部分优化到两个射击模具制造，2K霉菌测试和串行2K零件生产。

垂直整合

单源，垂直集成的stebro模具使新工具更容易，更灵活地过渡到注射成型。在该工具的船舶到其家中的船舶或启动您的计划或填写未来的生产之前，我们可以轻松地处理您的T-0，T-1样品和短期生产。了解有关我们内部2K注射成型的更多信息。

两次成型的优势，缺点和应用

2K注射成型的优势

Stable production processes and high efficiency
较低的零件成本与过度和组装零件相比
Enhanced tactile and cosmetic product features
High precision and stable part quality
Improve the touch feel
Expanded design possibilities
Optimum bonding with minimum time and labor

Disadvantage of 2K Injection Molding

2K injection mold and 2K injection molding process cost is higher than single injection molding, but the cost can be covered because of the assembly cost.
2塑料材料必须b之间的组合e good

Applications of co injection molding:

Soft-Touch enhancements, combining thermoplastics and silicone in one component, such as hand tools, writing instruments and toothbrushes
Performance improvements, combining different material properties for an Ideal solution.
Enhance cosmetics features, permanent graphics through the use of additional colored resins.

Stebro Mold is pleased to advise you as a stong 2K injection mold manufacturing and 2K injection molding partner. We will work with you to optimize the part design, select the suitbale material, choose the cost effective 2K mold and two shot molding solution.
