How Custom Spray Pumps Support OEM and ODM Perfume Packaging Development

A 50 ml glass flacon with a 15/415 neck can be closed by a crimp pump, a crimpless pump or a screw pump, and once the glass mold is cut that choice is no longer free. Perfume packaging development runs in the opposite direction to the way it is usually described: the pump specification, not the bottle silhouette, decides whether an OEM or ODM program can be tooled, filled and shipped on schedule. Zhangjiagang XinYe Chemical Sprayer Co., Ltd. (XinYe), a perfume spray pump manufacturer founded in 2006 in Zhangjiagang, China, builds its catalog around the four values that control that decision.

What follows covers how a custom spray pump behaves inside an OEM brief, where an ODM program saves tooling money, which tolerances cause leaks after filling, and how to sequence sampling so a fragrance launch does not stall at the pump.

The four numbers that freeze a custom spray pump specification

A custom spray pump is specified by four numbers: neck finish, ferrule or thread diameter, dosage per actuation and dip tube length. Fix those four and the collar profile, cap finish, actuator color and bottle silhouette all stay open for design work.

Order matters. The neck finish comes first because it is cut into glass and into the aluminum collar; the other three follow from it.

• Neck finish. A finish such as 13/415, 15/415, 18/415 or 20/410 carries two pieces of information: the neck diameter in millimeters and the thread family. A 15/415 bottle and a 15/420 bottle are not interchangeable even though both read as 15 mm.
• Ferrule or thread diameter. Crimp pumps are named by ferrule size, which is why the FEA13, FEA15, FEA18 and FEA20 series correspond to 13 mm, 15 mm, 18 mm and 20 mm ferrules. Screw pumps are named by neck finish instead, so the same manufacturer lists both a 15/415 screw pump and an FEA15 crimp pump.
• Dosage per actuation. Fine mist perfume pumps usually meter between 0.05 mL and 0.12 mL per stroke. State that target in milliliters in the brief; chamber volume, spring rate and actuator orifice are then tuned together to hit it.
• Dip tube length. The tube is cut so its end sits a short distance above the base of the bottle, and it is matched to the internal height of the glass rather than to its nominal capacity.

The variable sitting underneath all four numbers is viscosity. An alcohol-based fragrance that is 70 percent ethanol by volume behaves nothing like a jojoba or argan oil blend. A pump that produces an even, clean mist on eau de parfum can deliver a coarse spray on a heavier oil, because the chamber fills more slowly and the return spring has less time to reset between strokes.

Crimp, crimpless or screw: matching the pump family to the program

Crimp pumps fit OEM programs that fill and crimp on an automated line, while crimpless and screw pumps fit ODM programs where the brand or contract filler assembles the bottle without a crimping head.

XinYe's catalog splits along exactly that line. Crimp pumps cover the FEA13, FEA15, FEA18 and FEA20 series. Crimpless pumps cover FEA13, FEA15 and FEA20 plus a customized crimpless body. Screw pumps cover the 12/415, 13/415, 15/415 and 18/415 families, including an aluminum screw spray pump and a plastic version of the same interface.

The table is the first filter in a sourcing conversation, not the last. Two 18/415 screw pumps can share a neck finish and still differ in outer diameter, actuator height and dosage, so buyers should compare pump drawings rather than family names. The same logic drives the 15/415 screw pump versus crimp pump comparison, where the deciding factor is not the neck but who owns the assembly step.

Crimpless pumps exist because a brand or filler sometimes owns no crimping head, no setting-force control and no wish to buy one. The retention geometry changes; the gasket and spray chamber do not. That makes the family a practical first choice for ODM launches, gift sets and projects filled in more than one country, and it keeps the neck interface open until the bottle drawing is signed off.

Why a vertically integrated supplier shortens the OEM sampling loop

A supplier that owns aluminum stamping, injection molding, anodizing and automated assembly can shorten a pump sampling loop from weeks to days, because every interface in the closure stack is measured in the same building.

XinYe was founded in 2006 and runs three production bases: the Zhangjiagang headquarters, a Zhangjiagang branch plant and a Huai'an branch. The company reports a combined site area of 100,000 square meters and 250,000 square meters of building area, with more than 600 employees, 60 senior managers and close to 100 staff in quality management and technical development. Its stated production chain runs from aluminum stamping and injection molding through aluminum surface anodizing to automated assembly, and the company states that it holds ISO 9001 quality management certification.

Those figures matter for one practical reason: tolerance stack-up. When a ferrule comes from one vendor, a collar from a second and a cap from a third, each part arrives inside its own tolerance band, and the stack can consume the whole clearance between collar and bottle shoulder. A plant that stamps the collar, anodizes it, molds the pump body and assembles them can measure that stack on one bench and move a few hundredths of a millimeter on a single part before shipping a sample.

It also changes how a change request is handled. Moving a collar from a bright anodized finish to a matte one, or a pump from a 15 mm to a 20 mm ferrule with a larger discharge, is an internal rework note when one plant holds the tooling, and a fresh quotation round when three suppliers do.

Buyers who want the whole neck and ferrule range in one view can start from XinYe's perfume spray pump range, which lists crimp, crimpless and screw families side by side, including 13/415, 15/415 and 18/415 screw pumps with outer diameters of 16 mm, 17.2 mm and 18 mm.

Collars and caps: where a pump program becomes a brand program

A perfume closure is a three-part stack of pump, collar and cap, and all three must be dimensioned from the same neck finish drawing even when they are ordered from different suppliers.

The collar sits at the shoulder of the bottle and is the aluminum surface a customer touches first. XinYe's collar range covers a straight collar for pumps, a stepped collar, a grooved stepped collar, an embossing collar and a customized collar, with model numbers that encode the geometry: XYZT17-05-15-6-22-8-4 describes a stepped aluminum collar sized for a cosmetic perfume bottle, while XYZT17-3-14DBSNG is supplied in gold and silver anodized finishes.

Caps are where ODM programs usually save the first round of tooling. A straight aluminum cap in a standard diameter, such as the minimalist XYLZ18-6-32 built for luxury glass fragrance bottles, can be reused across two or three references in the same line, while the XYLZ20-6-34 cap in multiple colours serves both fragrance and essential oil bottles. A bespoke cap with an embossed logo needs its own die and its own sampling cycle.

A five-step validation path from sample to shipment

Five checks separate a pump that sprays correctly on a bench from a pump that still sprays correctly after a year in a retail box.

1. Freeze the drawing. Record neck finish, ferrule or thread diameter, dosage target, dip tube length and collar interface on a single sheet before any sample is built.
2. Build functional samples in real materials. Thirty to fifty filled pieces expose spray pattern problems that a water test hides, because ethanol content and viscosity change both the mist and the seal.
3. Test spray-out and compatibility. Check dosage consistency across the sample, spray pattern symmetry, and leakage with the bottle inverted for 24 hours and held at elevated temperature for 48 hours.
4. Simulate transport. ISTA 3A parcel testing and ASTM D6653 vacuum methods reproduce the pressure and vibration a filled bottle meets between the filling line and the retail shelf.
5. Verify the crimp setting on the line. Crimping force affects seal integrity as much as the gasket does, so the setting is confirmed against the first production batch, not just against the sample.

Where the filler works under ISO 22716 cosmetics GMP, the incoming inspection record for each pump batch becomes part of the batch file, which is one more reason to keep dosage and neck finish fixed across a production run.

Practical questions buyers raise before committing a pump program

Four questions come up in nearly every OEM or ODM pump conversation, and each has a short, technical answer.

Can one pump body serve two bottle sizes?

Yes, when neck finish, dosage and dip tube length are identical. The 13/415 screw family shows how far that goes: the same thread accepts a pump with a 16 mm outer diameter or a slimmer 13 mm body, and only the dip tube and actuator change between bottle capacities.

How early should a spray pump supplier join an OEM project?

Before the glass drawing is released for mold cutting. Neck finish changes after the mold is cut require a new mold, while pump-side changes such as ferrule diameter, dosage or actuator finish are rework inside one plant.

Do crimpless pumps seal as well as crimped pumps?

The seal is formed by the same gasket compressed against the same glass neck; only the retention method differs. Validate both on the same filled bottle, inverted for 24 hours, before choosing between them for a production run.

What decides the cost of a custom spray pump?

Tooling, not the pump. Standard FEA13 to FEA20 crimp bodies and 12/415 to 18/415 thread bodies already exist as molds, so cost concentrates in the parts that need new work: the collar profile, the cap die and any bespoke actuator.
