Molding Wireless Innovation

Shaping the Future: How CHOWSONS Turned a UK Client’s Wireless Vision into Reality Through Mold Development
When Transformation Meets Challenge: A 20-Inch Suitcase-Sized Mold Design Project
In the manufacturing world, client trust is built upon successive successful deliveries. We have a UK-based security product client who had been entrusting CHOWSONS with metal housing and circuit board production for years. However, 2018 marked a turning point in their company history—they decided to enter the wireless product realm, investing substantial R&D resources to upgrade their product line from wired to wireless transmission. This represented not just a technological leap, but a major strategic transformation. Within this transformative journey, an unprecedented mold design challenge awaited the CHOWSONS team to conquer.

This transformation project involved seven circuit boards of varying sizes, a core initiative highly prioritized by the client's senior management. Given CHOWSONS' profound expertise in SMT production, the client unhesitatingly entrusted us with orders for all seven boards. However, the real challenge was just beginning—since metal housing create a shielding effect on wireless signals, the new wireless mainframe couldn't fit into existing metal casings and required a redesigned plastic housing approximately the size of a 20-inch suitcase. This dimension far exceeded all our previous plastic component manufacturing experience.
From Circuit Boards to Mold Design: Cross-Domain Integration Expertise
When the client assigned us this oversized mold design for injection molding task, we clearly recognized this would be a tough battle. The 20-inch suitcase dimension meant mold structure complexity would increase exponentially—from cavity design and cooling system configuration to injection pressure calculations, every element required precise control. The slightest error could cause product deformation, sink marks, or insufficient strength.

However, this "knowingly facing the tiger in the mountains" spirit drove the CHOWSONS team to embrace the challenge. After careful evaluation, our structural engineering team, though acknowledging the task's difficulty, remained confident in overcoming obstacles. This confidence stemmed from years of accumulated mold design experience and deep understanding of injection molding craftsmanship. More importantly, we understood this project's significance to the client—this concerned not just one product's success or failure, but the entire company's transformation strategy.
The Mold Design Marathon: A Refining Process of Multiple Modifications and Validations
Large-scale mold design is never achieved overnight but requires a marathon of patience and perseverance. To ensure the final product perfectly met client requirements, the CHOWSONS team embarked on an extended and meticulous development journey. From initial 3D modeling design and structural strength analysis to mold flow analysis simulation, every step underwent repeated verification.

Throughout development, we created multiple test models, conducting physical validation for different structural solutions. Sometimes to optimize rib positioning for enhanced strength, sometimes to adjust draft angles ensuring smooth production, and sometimes to correct dimensional deviations achieving precise fit. Each modification represented a step toward perfection; every model embodied engineers' commitment to quality.

The most critical aspect of this process was mastering mold design for injection molding techniques. Due to the product's large size, plastic flow paths during injection were lengthy, making temperature control and pressure balance extremely complex. We employed advanced mold flow analysis software to simulate plastic filling under different gate positions and injection parameters, identifying optimal process conditions. Simultaneously, cooling channel design required careful planning to ensure uniform cooling of the large mold, preventing warpage deformation.
From SMT to Plastic Injection: Perfect Demonstration of One-Stop ODM Services
This project's success fully showcased CHOWSONS' comprehensive capabilities as an ODM manufacturer. From initial SMT circuit board assembly to subsequent large-scale mold design and plastic injection production, we provided the UK client with a genuine one-stop solution. Clients didn't need to distribute orders among multiple suppliers, worry about coordination issues between different manufacturers, or struggle with quality consistency concerns.

At CHOWSONS, we perfectly integrate electronics and mechanics. While seven circuit boards were efficiently produced on our SMT production lines, the large plastic housing was simultaneously manufactured in our injection molding workshop. This vertical integration capability not only significantly shortened project development cycles but also ensured perfect compatibility between product components. When circuit boards met housings on assembly lines, everything fit precisely as expected—this represents the highest realm of ODM services.

After multiple modifications and validations, this approximately 20-inch suitcase-sized plastic housing finally achieved mass production. When the first batch emerged from production lines, all project engineers felt that sense of accomplishment—this was not merely a technical victory but the perfect combination of trust and professionalism. The UK client's wireless product generational transformation proceeded smoothly, and CHOWSONS once again proved its exceptional capabilities in large-scale mold design for injection molding.
