Why ABS Is the Default Body Material
Walk through almost any shower head factory and you will find the same starting point: ABS resin. At ZHONGHE's plant in Cixi, Ningbo, ABS is the main material for hand shower bodies, overhead shower shells, brackets, and most internal components. ABS flows well in injection molding, reproduces fine detail such as nozzle plates and thread forms, and comes off the tool with a smooth surface that needs little rework.
ABS has a second advantage that matters even more in sanitary ware: it accepts electroplating. ABS is the standard plastic substrate for chrome-like electroplated finishes, which is why the vast majority of "chrome" shower heads on the market are plated ABS rather than solid metal. ZHONGHE runs 15 injection molding machines and four assembly lines around this material, producing more than 3 million units per year.
- Molds easily and reproduces fine detail at high volume
- Accepts chrome-like electroplating and spray-painted colors
- Light in the hand and inexpensive to ship
- Cost-efficient once tooling is amortized over volume production
Where 304 Stainless Steel Fits
All-metal shower heads exist, but in mainstream OEM production 304 stainless steel usually appears in one specific place: the face plate. On selected ZHONGHE models, a stamped 304 stainless steel face plate covers the spray face, putting a genuine metal surface where the user looks and touches most. 304 is the grade commonly specified for wet environments.
For buyers, a stainless face plate is a way to move a product up a price band without paying for all-metal construction. It adds material and stamping cost and modest weight, but far less of both than a solid metal body would. Many brands pair a stainless face with a plated ABS body so the product reads as metal while staying competitive on landed cost.
Why PC Is Used for Transparent Chambers
PC (polycarbonate) is chosen wherever transparency is part of the product story. The most common application is the filter chamber: a clear PC handle or window that lets the user see the mineral bead blend or replaceable cartridge inside. ABS is opaque, so it cannot do this job; PC combines clarity with the toughness a daily-handled part needs.
Transparency also does commercial work: a visible filter tells the shopper at a glance that the product treats water, and it makes the replacement cycle self-evident. This is why ZHONGHE's filter shower heads at /products/filter-shower-heads/ typically pair an ABS body with a clear PC chamber.
Material Comparison at a Glance
The table below summarizes how the three materials divide the work in a typical shower head program. Cost and weight notes are qualitative; ZHONGHE quotes each project against its actual specification.
| Material | Typical parts | Finish options | Relative weight | Relative cost |
|---|---|---|---|---|
| ABS resin | Body, shell, nozzle plate, internal parts | Electroplating, spray painting, bare molded color | Light | Lowest of the three |
| 304 stainless steel | Face plates on selected models | Brushed or polished metal surface | Adds weight where used | Higher per part |
| PC (polycarbonate) | Transparent filter chambers and windows | Usually left clear; can be tinted | Light | Moderate |
How Material Choice Affects Cost, Finish, and Weight
Material drives cost through three doors. First, the resin or metal itself: stainless steel costs more per part than ABS, and PC sits between them. Second, processing: electroplating adds steps and cost over bare ABS, while a stainless face plate adds stamping and assembly operations. Third, logistics: heavier products cost more to freight, which matters most at e-commerce price points.
Finish options are also material-bound. ABS opens the full menu of chrome-like electroplating, painted colors, or bare molded color. Stainless steel brings its own brushed or polished look and needs no plating. PC is generally left clear, because clarity is the reason it was chosen. Weight is a perception tool: a slightly heavier head can feel more premium, but every added gram travels in the carton, so programs balance the two deliberately.
What to Specify in an RFQ
A material-complete RFQ shortens quoting because the factory does not have to guess. If you already have a reference product, ZHONGHE also offers a photo-match service: email a photo to [email protected] and the team checks it against a catalog of 115 models in 10 categories. Details on the development process are at /oem-odm/.
- State the body material, or confirm ABS as the default for the main body and internal parts.
- Decide the spray face: plated ABS nozzle plate or a 304 stainless steel face plate.
- Mark any transparent parts, such as a PC filter chamber, and what should be visible inside.
- Assign a finish to each visible part: electroplating, a paint color reference, or bare molded color.
- List required tests, for example salt spray testing on selected finished parts.
- Give your target quantity; ZHONGHE's MOQ starts from 2,000 units for many projects.
