Customer Projects

Customer projects: four packaging programmes, described in detail

Skincare, personal care, household cleaning and premium cosmetics. Each record gives the material, the tooling route, the sampling round and the volume that shipped — not a wall of logos.

Evidence

Four programmes, one manufacturing base

These are four packaging programmes Shijin manufactured and shipped. They are published because a supplier capability claim is worth very little next to a record of what was actually produced, sampled and reordered.

Quick answer

The four programmes below cover PETG serum droppers at 15–50 ml, HDPE body wash at 200–500 ml, a 30% recycled-content PET trigger spray, and a custom 30 ml and 50 ml PETG jar on a private tool.

What stays constant across all four: packaging manufactured in-house since 2003 from 15,000 m² of production space in Shenzhen and Huizhou, 2,000+ existing molds, and a capacity of 200,000 pieces a day.

Client names, artwork and unit prices are covered by confidentiality agreements and are not published. The technical record of each project is published in full.

How to read this

What is published, and what is not

A case study is only useful if you can tell which parts are evidence and which parts are withheld. This is the line we draw on every project page.

Not published on these pages
  • ▸The client’s name, brand and artwork. Every project page is written from the technical record, not from a marketing brief.
  • ▸The unit price. Resin grade, cavity count and decoration all move the piece price, so a number quoted for another buyer’s specification would be misleading rather than useful.
  • ▸Anything we cannot evidence. Where a figure is not in the project record, the page says so instead of filling the gap with an estimate.

What is published: material, size range, the engineering problem that had to be solved, the sampling round, the order quantity and what happened on reorder. Those are the things that tell you whether your own project is a fit.

How we work

From first message to shipping carton

Every one of the four programmes above ran through the same five stages. Knowing the sequence in advance is what lets you plan internally before you commit to anything.

1

Brief and feasibility

You send capacity, material preference, decoration and target quantity. We come back with what is possible from the 2,000+ existing molds, what would need a new mold, and an honest indication of cost and lead time. No obligation at this stage.

2

Quotation and mold decision

If a private mold is required, tooling is quoted separately from the unit price so you can see exactly what you are paying for. An existing mold avoids that cost entirely — worth searching before anything new is commissioned.

3

Sampling and approval

Samples are produced for your sign-off on shape, colour, finish and decoration. Nothing enters mass production until a physical sample is approved — the single biggest protection against an expensive mistake.

4

Production and inspection

Molding, decoration and assembly run against the approved sample, with IQC, IPQC and OQC gates in between. A third-party inspector is welcome, and a live video walkthrough can be arranged during the run.

Packing and delivery

Cartons are counted and marked against the packing list, then shipped EXW, FOB or on your nominated forwarder. Export documents are prepared for your market, and batch records stay on file after delivery.

Scope

What every project includes

These are not add-ons or premium tiers. They are part of how the packaging is built, whichever of the four projects you look at.

Bottle and closure together

Bottles, caps, pumps, sprayers and droppers are sourced and fit-tested as one assembly, so the seal is our responsibility rather than a dispute between two suppliers.

In-house decoration

Silk screen, labelling, hot stamping and spray coating are handled in-house, so decoration lead times stay inside our control instead of depending on an outside print shop.

Documented quality

Inspection records for every batch, retained samples, and third-party test reports arranged for your destination market when they are required.

Consistency on reorder

Colour, wall thickness and print position are held to the approved standard sample. That is what makes a fourth reorder match the first.

FAQ

Before you start a project

Can you make my bottle without a new mold?+

Often, yes. We hold 2,000+ existing molds, and many projects are built on the closest match plus custom colour, decoration and closure. That removes the tooling cost and shortens the timeline considerably. Send the capacity and shape you want and we will tell you honestly whether an existing mold is a good fit or whether a private mold is the better route.

What is the minimum order quantity?+

MOQ depends on the product and the mold. For custom accessories and closures, orders start at 5,000 pcs in white, black or natural, or 10,000 pcs for custom colours. Stock-mold bottles can sometimes be supplied in smaller trial volumes with a start-up fee — ask, and we will tell you what is genuinely possible rather than quoting a blanket rule.

Do I have to pay for the mold up front?+

Private tooling is quoted and invoiced separately from the unit price, so you can see what you are paying for and what it buys. Many clients prefer that to a tooling cost buried in the piece price. Where a project is large enough, amortising tooling across the order is a conversation worth having.

Can I use my own artwork and colours?+

Yes. Silk screen, labelling, hot stamp and spray coating are all done in-house, so your artwork is applied under our own inspection rather than by an outside printer. Colour is matched against an approved masterbatch sample, and a physical standard chip is kept for reorder consistency.

How do you protect my design if the mold is custom?+

Custom tooling is made for your project and can be marked with your own identification. We do not resell a client’s private mold to another customer. If your brand requires it, we will sign your NDA before receiving technical drawings — that is standard practice for us, not an unusual request.

What information do you need to quote accurately?+

Five things: target capacity, material preference or the product it will hold, closure type, decoration requirements, and order quantity. Add your destination country and any deadline you are working to, and the quote comes back with the right export documentation instead of needing a second round.

Do you supply samples before a full order?+

Always. Nothing enters mass production until a physical sample has been approved for shape, colour, finish and print. Sampling from an existing mold typically runs 3–10 days; a new tool is a longer programme and is scheduled separately. You will be told which applies before you commit.

Which countries do you export to?+

Shijin ships to buyers in 30+ countries, with long experience in North America, Europe, Southeast Asia and the Middle East. Export paperwork — declarations, test reports and translations — is prepared in English as standard, because a delayed customs clearance costs far more than the document itself.
