Overmolding & Insert Molding of Exquisite Quality
包覆成型和嵌件成型的材料
以下的通用材料适用于嵌件和包覆成型注塑。
以下是通用橡胶包覆成型和嵌件成型材料：
如果标准材料无法满足您定制注塑件的需求，添加剂和纤维可以增强材料性能。
包覆成型与嵌件成型
包覆成型和嵌件成型工艺是用于将多种材料或组件集成到单一模塑件中的专业注塑成型技术。
包覆成型
包覆成型是在现有零件上模制一层材料，以增强美观性、握持感或功能性。基材零件成型后，手动放入包覆模具中，用热塑性塑料或液态硅胶进行包覆成型。
它常用于工具手柄、电子设备外壳、牙刷和剃须刀。非常适合在刚性基材上创建柔软、灵活的外层部件。
嵌件成型
嵌件成型是类似的工艺，但它涉及使用一个预成型部件（通常是金属），将其放入模具中。然后用热塑性树脂包覆该预成型部件以制造最终组件。
适用于需要强度和导电性的应用，例如电气组件、汽车零件和医疗设备。它用于增强最终产品的结构完整性和耐久性。

How an Overmolding or Insert Molding Project Works
Early review of geometry, materials, and interfaces helps reduce tooling changes and production risk.
1. Review
We review the 3D model, substrate or insert, material requirements, annual volume, appearance, tolerances, and use environment.
2. Engineer
DFM covers bonding, mechanical retention, shutoffs, insert location, wall thickness, gates, venting, shrinkage, and handling.
3. Validate
After tooling and sampling, parts are evaluated against agreed dimensional, visual, bonding, sealing, and functional criteria.
4. Produce
Approved settings and inspection requirements support repeatable molding, secondary operations, packaging, and delivery.
What to Send for an Accurate Quote
- 3D CAD files (STEP preferred) and a 2D drawing with critical tolerances
- Substrate, overmold resin, or insert specifications—and any required material certifications
- Expected annual volume, order quantity, colors, textures, and cosmetic requirements
- Bonding, pull-out, sealing, electrical, temperature, chemical, or other functional requirements
- Target schedule plus any assembly, inspection, packaging, or shipping requirements
Overmolding and Insert Molding FAQ
What is the difference between overmolding and insert molding?
Overmolding adds one molding material over a previously molded substrate. Insert molding places a prepared component—often metal, electronic, or another solid part—into the mold so resin forms around it. Some products use both approaches.
How do you choose compatible overmolding materials?
Selection depends on chemical adhesion, processing temperatures, shrinkage, hardness, use environment, regulatory needs, and whether the design uses mechanical interlocks. Material pairing should be reviewed before tooling is finalized.
Can you mold around threaded metal inserts or electronic components?
Yes, when the insert can tolerate molding pressure and temperature and its geometry supports secure positioning and sealing. We review retention, orientation, flash control, handling, and inspection requirements during DFM.
How is bond strength verified?
The acceptance method depends on the product. It may include visual inspection, peel or pull testing, torque or push-out testing, leak testing, dimensional checks, or a customer-defined functional test.
Can Rilong build the mold and manufacture the finished parts?
Yes. Rilong supports mold design and manufacturing, sampling, process validation, production molding, inspection, secondary operations, assembly, packaging, and shipment from one manufacturing team.
