Simply Define
the Process of Insert Molding

Insert molding means inserting a prefabricated component, such as a metal insert or another part, into a mold cavity and then injecting molten plastic around it to make a single, integrated piece. This method increases part strength, decreases assembly time, and enables for more complicated shapes. LUSHI provides insert molding with accuracy, using innovative technology and materials to assure smooth integration and high-quality finished products according to customer specifications.

Insert molding offers advantages such as stronger part strength, lower assembly costs, improved part uniformity, and more freedom in design. It enables the integration of a variety of materials, including metals and electronics, into plastic components. Insert molding is used in a variety of industries to improve product performance, durability, and manufacturing efficiency.

Benefits of insert molding service

Insert molding provides various advantages, including increased part strength, shorter assembly times, and greater design flexibility. Integrating inserts directly into molded parts removes the need for additional assembly stages, lowering costs and enhancing overall product reliability. Furthermore, it enables the production of complicated geometries and multi-material components, broadening design options for a variety of applications.

Limitation of Overmolding Service

Insert molding has its drawbacks, including higher expenses for tooling due to the necessity for precision molds that can accommodate inserts. In addition, complex part geometries might make it difficult to achieve consistent material distribution, which can lead to flaws. Limited material options and compatibility difficulties with insert and molding materials may further limit design flexibility.

Design tips for plastic insert molding

Material Compatibility

Ensure that the insert and molding materials are suitable to avoid adhesion concerns or material degradation during the molding process.

Insert Design

In order to avoid movement or misalignment during molding, optimize the insert's design for simple integration into the mold and secure installation.

Gate Placement

Place gates in an intentional manner to reduce insert stress concentrations and provide even material flow for reliable part quality.

Undercuts

Reduce the number of intricate details or design undercuts that could interfere with part ejection or complicate mold design, creating production issues.

Thermal Management

Consider thermal expansion and contraction of materials during molding to prevent warping or distortion of inserts, especially with temperature-sensitive materials.

Quality Control

To maintain quality and consistency throughout the molding process, use inspection processes to confirm insert location, integrity, and part dimensions.

Post Processing for Injection Molded Parts

LUSHI's post-processing for plastic parts includes surface finishing, painting, and plating, which enhance aesthetics, functionality, and durability, ensuring high-quality, tailored solutions for various applications and industry requirements.

01

Standard Finish

Tooling or mold polishing are common methods used to generate a smooth or matte surface texture for injection molded products. These finishes are excellent for many sectors without the need for extra surface treatment since they offer a clean look and basic functionality for a wide range of applications.

02

SPI A

The SPI grade A indicates a high-quality finish suitable for applications requiring a polished appearance, minimal surface defects, and fine texture. It ensures parts meet aesthetic and functional standards.

03

SPI B

SPI B surface finish standard denotes a medium polish finish with clearly visible tool marks eliminated. It provides a smooth surface ideal for general-purpose uses when minimal roughness and visual appeal are required.

04

SPI C

SPI Class C refers to a surface finish standard for injection molded parts. It involves a medium level of polish, suitable for parts requiring a smooth finish with some visible tooling marks acceptable. This standard is commonly used in consumer goods and industrial applications.

05

MoldTech (Mold Texturing)

Injection molds are given complex patterns or textures using a process known as mold texturing, or mold technology. Through improved surface smoothness, grip, and overall aesthetics, this procedure improves the look and performance of injection molded parts for a variety of applications across industries.

06

VDI (Verein Deutscher Ingenieure)

The VDI (Verein Deutscher Ingenieure) offers rules and standards pertaining to design, manufacturing, and quality assurance for injection molded products. The production of injection-molded components is guaranteed to be consistent, reliable, and compliant with industry best practices thanks to these standards.

07

Laser Engraving

Laser engraving offers precise and permanent marking solutions, ideal for part identification, branding, or aesthetic enhancements. It provides high-resolution designs with minimal material removal, ensuring durability and maintaining part integrity.

Precision manufacturing for custom plastic injection lolding service

Design for Manufacturing (DFM)

DFM in injection mold manufacturing ensures efficient production, lowers costs, and improves product quality. By improving designs, DFM addresses possible concerns early on, expediting the entire production process.
