Customer Case | Vertical Injection Molding Machine Application

This customer case introduces how Suzhou Lizhu Machinery Co., Ltd. provided a production upgrade solution with vertical injection molding machines for an automotive wiring harness manufacturer in Mexico.

Based on the customer's product characteristics, molding process requirements, and actual production conditions, Suzhou Lizhu Machinery provided standard vertical injection molding machine and vertical insert molding machine solutions to help the customer improve production issues including unstable equipment performance, low manual operation efficiency, and product consistency fluctuations.

As a professional manufacturer of vertical injection molding machines, Suzhou Lizhu Machinery has been serving overseas manufacturing customers for many years, providing reliable plastic molding equipment and technical solutions for industries including automotive components, electronic products, and precision plastic parts.

This successful project further demonstrates the application capability of Suzhou Lizhu vertical injection molding machine in automotive wiring harness and precision insert molding applications.

Customer Background: Automotive Industry Development Drives Wiring Harness Production Upgrade

The customer in this project is an automotive wiring harness manufacturer located in Mexico, specializing in the production of automotive connectors, wiring terminals, plastic housings, and metal insert molded components.

In recent years, with the continuous development of the North American automotive manufacturing industry, demand for automotive component suppliers in Mexico has continued to grow, leading to increased production requirements from the customer.

With the expansion of production capacity, the customer's existing injection molding equipment gradually became unable to fully meet new manufacturing requirements.

During daily production, the customer mainly faced the following challenges:

• Reduced equipment stability during long-term operation;

• Need for higher positioning accuracy during metal terminal insertion;

• Product consistency variations between production batches;

• Low efficiency of manual insert placement;

• Production interruptions caused by equipment maintenance.

Because automotive wiring harness components must meet strict quality requirements from vehicle manufacturers, production stability and product consistency became key concerns for the customer.

To improve production efficiency while maintaining stable product quality, the customer started looking for a more suitable vertical injection molding machine solution.

After evaluating different equipment suppliers, the customer finally selected Suzhou Lizhu Machinery as its long-term equipment partner.

Equipment Solution: Vertical Insert Molding Solution Designed for Automotive Wiring Harness Production

At the beginning of the project, the technical team of Suzhou Lizhu Machinery conducted a detailed analysis of the customer's product structure, production process, and factory environment.

Based on the characteristics of automotive wiring harness components requiring metal terminal insert molding, the project adopted a standard vertical injection molding machine as the main production equipment and a vertical insert molding machine for precision insert molding applications.

The standard vertical injection molding machine adopts a vertical clamping structure with an open working area, allowing operators to place terminals and metal inserts conveniently and improving production operation efficiency.

The compact machine design helps reduce floor space requirements and allows customers to optimize their workshop layout.

For automotive connectors and wiring harness components requiring high dimensional accuracy, the machine control system allows precise adjustment of injection speed, injection pressure, and holding pressure parameters, ensuring a more stable molding process.

The vertical insert molding machine effectively meets the production requirements of combining plastic materials with metal components, improving product consistency and reducing quality fluctuations during production.

Project Implementation: Equipment Setup and Training Support Smooth Production Start

After the equipment arrived at the customer's factory in Mexico, Suzhou Lizhu Machinery provided technical support for machine installation, production commissioning, and operator training.

During the commissioning process, engineers optimized injection parameters according to the customer's actual products to ensure stable machine performance.

At the same time, training was provided for customer operators to help them become familiar with machine operation procedures.

After trial production verification, the customer officially introduced the new vertical injection molding machine into mass production.

After operation, the customer's production process became smoother, equipment adjustment time was reduced, and production stability was improved.

Application Results: Improved Production Stability Meets Automotive Supply Chain Requirements

After applying the Suzhou Lizhu vertical injection molding machine solution, the customer achieved improvements including:

• More stable injection molding production;

• Improved product consistency;

• Higher insert molding efficiency;

• Optimized manual operation process;

• Easier equipment maintenance.

The new equipment solution helped the customer improve production management efficiency and better meet continuous production requirements for automotive wiring harness components.

At the same time, stable equipment performance helped the customer respond more effectively to changes in automotive supply chain demand.

Customer Feedback: Reliable Equipment Supports Long-Term Mass Production

The customer's production team commented that the standard vertical injection molding machine and vertical insert molding machine provided by Suzhou Lizhu Machinery are easy to operate, stable in performance, and suitable for long-term automotive wiring harness production.

Compared with the previous equipment, the new machines have shown clear improvements in production stability, operation convenience, and maintenance management.

Currently, the customer has applied Suzhou Lizhu vertical molding machine solutions to multiple automotive wiring harness projects and plans to further expand equipment investment according to future production demand.
