Speaker factory introduces dual-core linear internal magnetic circuit machine, 8-minute drying + 1500PCS/H capacity to crack the production bottleneck.

A professional speaker driver manufacturer has long been plagued by low production efficiency and insufficient capacity to meet order demand for magnetic circuit assemblies. This issue is particularly acute during the machining of core components for speaker driver magnetic circuits, where the drying process on traditional equipment takes over 15 minutes. This not only extends the overall production cycle but also leads to a severe backlog of work-in-progress. daily production capacity for magnetic circuit components was only 800 units, far from meeting the bulk order demands of downstream customers in the audio and car audio industries. More challenging still, due to the diverse specifications of U-shaped shells and magnets in speaker magnetic circuits, traditional equipment has poor adaptability to different sizes. Dimensional deviations often cause misalignment during assembly, resulting in a scrap rate as high as 81%. This not only increases raw material waste but also further delays delivery schedules.

To address these challenges, the company conducted extensive research and ultimately introduced a dual-core linear internal magnetic circuit machine. In terms of key specifications, this equipment’s drying chamber requires only 8 minutes for the drying process—a reduction of nearly 50% compared to traditional equipment—significantly shortening the production cycle for magnetic circuit assemblies and alleviating pressure on work-in-progress inventory. With a production capacity of 1,200–1,500 units per hour, the company’s daily output of magnetic circuit assemblies has surged to over 10,000 units, enabling it to easily handle peak order volumes during busy seasons and even accept large-volume orders that were previously turned down due to insufficient capacity.

In terms of dimensional compatibility, the dual-core design of the linear internal magnet circuit machine offers particularly significant advantages. For the core components of speaker magnetic circuits, the equipment supports U-shaped shells with a maximum diameter of 40 mm, while magnet and washer sizes cover the range from 9 mm to 30 mm, fully meeting the company’s production needs for mid-to-high-end speaker magnetic circuits — — whether it’s the small ∅9mm magnets used in compact Bluetooth speakers or the large ∅30mm magnets used in automotive speakers, the equipment can precisely accommodate them, eliminating the need for frequent mold or parameter adjustments. Changeover time has been reduced from 2 hours to 15 minutes, significantly enhancing production flexibility.

In addition, the equipment’s internal magnetic circuit assembly solution and three-step process further optimize the production of speaker magnetic circuits. The internal magnetic circuit assembly solution, designed with standardized steps, ensures the assembly precision of magnets, washers, and U-shaped shells, eliminating errors associated with manual assembly and raising the product yield rate from 92.1% to 99.1%; Meanwhile, the three-step process streamlines the entire workflow from raw material pretreatment to finished product inspection, reducing redundant intermediate steps and making the production rhythm smoother.
