We specialise in silicone protective cases and pouches for vape devices. Structural design, mold making, injection molding and brand packaging are all handled in-house. No drawings needed — a physical sample is enough to start.

01CAPABILITIES
We do not outsource design, mold making or injection molding. Splitting those steps across vendors is what makes schedules and quality slip.
OEM / ODM Manufacturing
We build to your design, or to ours.
We run both OEM — production to your drawings or samples — and ODM, where our own verified design assets are supplied under your brand. Pre-validated molds for many device models shorten the initial development cycle.
Structural & Mold Design
From 3D modelling to mold design, all in-house.
The sequence runs device measurement → 3D scan → structural design → flow analysis → mold design. Case-specific issues such as magnetic closure, opening mechanisms and slide cores are reviewed directly by our in-house design team.
In-house Mold & Injection
Mold machining and molding never leave the building.
We own both mold machining equipment and injection molding machines, so mold revisions and mass production are managed on the same line. Trial-shot results feed straight back into the mold, which keeps the development cycle short.
Own-brand Product Development
Verified design assets, supplied under your brand.
IUYU maintains its own developed and validated case line-up. When launching a new brand, applying your branding to already-verified products removes the design and mold development steps entirely and cuts lead time significantly.
02MATERIAL
A protective case is about feel, recovery and the precision not to squeeze the device. IUYU selects different silicone grades by application.
Used for thin-wall cases that need precise dimensions and clarity. We handle this molding on our own line.
Used for thicker pouches and grips that need recovery and tear strength.
Two-shot molding bonds silicone with rigid resin, combining shape retention and grip.
03PROCESS
Tell us the device model, desired form and expected volume. We reply with feasibility and an estimated schedule.
We measure the device or work from your drawings to build a 3D model, and share the structural review with it.
Produced on our in-house mold line. Mold structure and gate position are fixed before machining starts.
Trial samples are checked for dimensions and closure feel. The mold is revised and re-verified if needed.
Produced to the approved sample, inspected, packed and shipped. Brand packaging is supported.

These four lines cover most requests. If the form is not decided yet, a reference image is enough to start a conversation.
Slim silicone case wrapping the device body. The screen area is open, and side buttons and the charging port remain fully usable.
Detachable neck lanyard so the device can be carried around the neck. Attaches to the loops on the case.
Small cap covering the mouthpiece. Handles hygiene and protection together.
New development from your drawings or a physical sample. Measured, tooled and produced end to end.

09FAQ
[MOQ]. It differs between projects requiring a new mold and projects reusing an existing mold, so we confirm which applies when you enquire.
No. IUYU only manufactures accessories such as protective cases, pouches and grips. We do not handle nicotine liquid, pods, refills or finished devices.
Where the customer bears the mold cost, ownership sits with the customer. Storage and transfer arrangements are agreed in the contract.
Around [duration] for a new mold. Where IUYU design assets can be reused, supply is possible within [duration] with no mold development.
Yes. Samples can be shipped for models where a mold already exists. For new developments, you can review at the trial-shot stage.
Yes. We have experience with export packaging, labelling and documentation, and can arrange material test reports to suit the destination market.
Yes, including RoHS and REACH on request. Tell us which items you need when you enquire.
Yes. We support Pantone-based colour matching and logo marking by embossing or printing.
