The outer housing is the part of a nasal irrigator that users see and hold every day. It carries the reservoir, pump and nozzle assembly inside, keeps water where it belongs, and defines how premium the whole device feels in the hand. For nasal care products the housing is also a hygiene-critical component: the material must be safe and non-toxic, surfaces must be smooth and easy to clean, and edges must be free of burrs that could scratch users during daily handling.
This solution page describes how Kunshan Maifeng Precision Industry Co., Ltd. (MIF) develops and produces custom nasal irrigator outer housings — from material selection and mold design through precision injection molding and multi-cavity mass production. The video and images below show the ABS housing and the molding process behind it.
Why ABS Is the Right Material for Nasal Irrigator Housings
The housing is molded from premium ABS. Compared with general-purpose resins, ABS offers high strength and toughness while remaining lightweight and long-lasting, which matters for a device that is picked up, refilled and rinsed every day. The grade we use is safe and non-toxic and meets the strict hygiene requirements of nasal care products, so end users can rinse with peace of mind.
ABS also responds well to molding and finishing: it fills fine texture consistently, holds a clean white color lot after lot, and polishes to the sleek, fine-grained surface that elevates the look and feel of the finished irrigator. Material data sheets and traceability documents are available per project, and for medical-adjacent programs our ISO 13485 certified production system can be applied.
Precision Molding for Stable Dimensions and a Flawless Surface
The housing is produced with a precision injection molding process to guarantee stable product dimensions, seamless assembly fit and a flawless surface finish. Every edge is smooth and burr-free, and the fine, sleek texture gives the finished nasal irrigator a premium look and feel.
Appearance-critical surfaces are where housings usually fail review — flow marks, sink marks, weld lines, gate traces and ejector whitening. We control these at the mold stage through gate location, polishing, venting and cooling design, then lock the process parameters once the approved standard is reached. Sample parts are inspected against the agreed appearance limit samples and dimensional reports before mass production.
Custom Mold Development and Multi-Cavity Mass Production
We support custom mold development from customer drawings or samples. Our engineering team reviews the structure for manufacturability, proposes gate and parting-line options, and builds multi-cavity mold solutions that enable high-efficiency mass production with consistent part quality across cavities.
Mold making and molding happen under one roof: more than 50 sets of mold manufacturing and processing equipment, and 36 single- and dual-color injection molding machines from 40 to 700 tons, including all-electric presses for stable, repeatable cycles. That combination turns custom design concepts into reliable plastic parts with a stable long-term supply.
Hygiene, Assembly Fit and Quality Documentation
Because the housing belongs to a hygiene-sensitive product, we keep material lots, mold data and molding parameters traceable, and retain inspection records for each production batch. For customers who position the 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.
On assembly, the housing must close cleanly over the internal modules, seal against water, and align with buttons and openings. We verify fit against the actual mating parts rather than the drawings alone — checking assembly force, gaps, sealing and overall hand feel — so the housing works the first time it is fitted on your production line.
Information to Confirm Before Starting a Nasal Irrigator Housing Project
- Housing structure and mating parts data — reservoir, pump and nozzle assembly, button and opening positions.
- Material requirements, including hygiene expectations and how the device will be cleaned during use.
- Target market and regulatory background, so the right material documentation is prepared.
- Appearance standards — acceptable gate and parting-line positions and appearance limit samples.
- Expected volumes, traceability requirements and the sample validation plan before mass production.
