The Factory Behind the Cases
CasesFactory is the export brand of Kexin New Materials (Guangdong) Co., Ltd. — a plastic case manufacturer in Guangdong Province, China, moulding since 2014. This page collects the facts a buyer needs to verify us: who the legal entity is, what happens under one roof, how a shipment is checked, and what we refuse to claim without evidence.

02 / Under one roof
Manufacturing Steps We Control
Mould design & build
Steel moulds for cases and moulded inserts are designed and finished in our mould workshop, then trialled on the machine before acceptance.
in-houseInjection moulding
PP and ABS shells moulded on the production hall machines, with colour changeover handled per batch.
in-houseInsert cutting
CNC knife-cut foam and EVA from the approved cutting file; multi-layer layouts stacked and bonded.
in-houseAssembly
Handles, latches, hinges, wheels, label plates and straps fitted; insert placed and lid closed for fit check.
in-houseInspection & packing
Dimension and appearance checks against the approved sample, then carton packing and palletising per the agreed packing plan.
EXW / FOB| Capability | What it means for a buyer | Status |

| First shot | Dimension, flash, sink, colour against approved sample | Sample retained |
| In-process | Visual and fit check during the run | Line check |
| Hardware function | Latch close/open, hinge alignment, handle fixing | Per order |
| Insert fit | Device placed in the cut layout before packing | Photo on request |
| Pre-shipment | Quantity, carton marks, packing plan, appearance | Packing list |
| Third-party | Your inspector at any stage, or pre-shipment | Their report |
/ Certificates
Published Only With Scope and Holder
A certificate number, its validity dates, the exact product scope and the legal entity named on it are published together — or not at all. Group-company certificates are labelled as held by the group and are never presented as this entity's own, and a scope limited to plastic tool boxes is not used to imply coverage of other product families.
This block stays marked pending until the certificate itself is supplied. It is the honest state, and it is also the state that protects you in a market where a wrongly claimed certificate is a legal problem for the importer, not only for us.
04 / Materials guide
PP vs ABS for Plastic Cases
The question arrives in every project meeting. The honest answer is that it depends on wall thickness, part geometry, colour, surface finish and the temperature the case actually sees — so we treat it as an engineering decision per model, not a brand preference.
| Consideration | PP — polypropylene | ABS |
|---|---|---|
| Stiffness / feel | Tough with more flex; good for shells that take a beating without cracking | Rigid with a harder surface; holds crisp edges and detail |
| Surface / appearance | Slightly softer sheen, common in dark industrial colours | Smooth, good for a finished consumer or brand look |
| Low temperature | Becomes stiffer in cold; behaviour depends on grade and wall thickness | Generally better retained toughness at low temperature |
| Weight | Lower density — lighter at equal thickness | Heavier at equal thickness |
| Cost driver | Material and cycle on the specific mould | Material plus often longer cooling on thick sections |
| Best used when | Tool cases, storage parts, price-sensitive volumes | Instrument cases, branded products, detail-rich geometry |
This table describes general material behaviour used for selection discussion. It is not a specification for any model. The material actually used is stated per model on its own page after engineering confirmation, and a specific grade can be quoted against your drawing.

Photographs From Our Own Facility
Are you a factory or a trading company?
Factory. Moulds, moulding, insert cutting, assembly and packing are done in our own facility in Guangdong, which is why mould records and measured dimensions exist for every published model. Third-party audits and pre-shipment inspection are welcome.
Can you supply a documented quality system or specific standards?
Send us the standard or customer requirement and we will tell you what our process already covers, what needs adding and what we cannot document — before you place an order rather than after.
Do you work under NDA?
Yes, for drawings, product concepts and customer lists. Customer-funded tooling is not used for another buyer's product.
Where are the cases shipped from?
Ex works from our Guangdong facility, or FOB to a Chinese port agreed in the order. We do not offer DDP and hold no overseas stock.
