Small plastic components often decide how well an electronic product works — and the battery holder inside a nasal irrigator is a typical example. It carries the battery, aligns the contact points, and fixes the position of the internal assembly, so its structure, dimensions and molding consistency directly affect whether the finished device assembles accurately and runs reliably.
This solution page describes how Kunshan Maifeng Precision Industry Co., Ltd. (MIF) develops and produces custom battery holders and charging brackets for nasal care devices — from material selection and mold development to sample testing and mass production. The video and images below show the ABS battery holder and the molding process behind it.
Why ABS Works Well for Battery Holders
The holder is molded from ABS, a material widely used in plastic component manufacturing thanks to its good impact resistance, dimensional stability and excellent molding performance. For a battery holder that must hold its position over thousands of insertion cycles and daily handling, these properties translate into a reliable structure and accurate, repeatable assembly.
ABS also fills thin ribs and small positioning features cleanly, which matters for a part with many clips, posts and connecting sections in a compact footprint. Material data sheets and traceability documents are available per project, and for medical-adjacent programs our ISO 13485 certified production system can be applied.
Structure Details: Positioning, Mounting and Connection Features
As the photos show, the battery holder features a carefully designed structure with multiple positioning points, mounting features and connecting sections. Each of these details has a job: the mounting posts locate the holder inside the housing, the connecting sections carry loads between parts, and the positioning features keep the battery and contacts aligned.
Details like these are only useful if they land in the right place every shot. Hole positions and clip dimensions are checked against the actual mating parts rather than the drawings alone, so the holder supports accurate assembly and stable positioning inside the finished nasal irrigator.
Custom Mold Development and Consistent Molding Quality
We specialize in custom injection mold design and manufacturing, as well as plastic injection molding production. From mold development and material selection to sample testing and mass production, we work closely with customers to meet their specific product requirements — gate and parting-line proposals come with the DFM review, and mold making happens in-house on more than 50 sets of machining equipment.
Consistent molding quality is what turns an approved sample into a stable supply. Once the sample is approved, process parameters are locked and monitored shot by shot, and each batch is checked against the required dimensions and assembly specifications before shipment.
From Sample Testing to Mass Production Supply
Whether you need battery holders, charging brackets, electronic housings, internal structural components or other custom plastic parts, we build the manufacturing solution around your drawings or samples. Our workshop runs 36 single- and dual-color injection molding machines from 40 to 700 tons, so the process that proves out on samples carries directly into volume production.
For customers who position the nasal irrigator as a medical or wellness device, our ISO 13485 quality system and ISO Class 7 cleanroom provide a compliant production path for the plastic parts, with lot-level traceability retained for each production batch.
Information to Confirm Before Starting a Battery Holder Project
- Battery and contact interface data — battery dimensions, contact type, insertion direction and retention requirements.
- Mating parts data — housing, charging bracket and PCB assembly that the holder must align with.
- Material requirements and any electrical, hygiene or cleaning expectations for the device.
- Target market and regulatory background, so the right material documentation is prepared.
- Expected volumes, critical dimensions, sample validation plan and traceability requirements.
