Custom silicone development for brands
ESKY SUPPLY works with consumer brands, merchandise companies and product teams — connecting branded product development with the silicone engineering needed to manufacture it.
Consumer-product thinking in front, engineering depth behind it
ESKY SUPPLY is a custom silicone product development and manufacturing partner based in Jinhua, Zhejiang, serving international B2B customers across consumer products, branded merchandise, electronics, lifestyle and functional applications.
We typically become involved before a product is fully production-ready. Projects may start from an idea, reference sample, sketch or CAD file, and move through material selection, DFM, tooling, sampling, production, quality control, assembly and packaging.
Our difference is not simply that we manufacture silicone products. We combine consumer-product development with deeper engineering capabilities such as LSR injection molding, silicone overmolding, silicone + plastic / metal integration, multi-material development and tooling support, helping customers move more complex products from concept to repeat production.
From early-stage product development to repeat production, ESKY supports projects that require both commercial product thinking and manufacturing depth.
Brand Experience
Selected brands and product teams we have supported.
Selected brand relationships are shown above. Other customer relationships are kept confidential under NDA.
Quality & Compliance
Quality systems and material/compliance support for different project requirements.
Tooling & Mold Development
CNC machining centers cut and maintain precision molds for custom projects, from first tooling through engineering changes.
Silicone Molding & Production
Molding machines run compression and LSR processes under controlled parameters for stable, repeatable output.
Quality Inspection
Incoming materials, in-process dimensions and finished parts are checked at dedicated QC workstations.
Assembly & Packaging
Finished parts are assembled, inspected again and packed to your specifications before shipment.
Factory operations
Manufacturing operations for custom silicone projects - tooling, molding, inspection and assembly, coordinated from our Jinhua base.

Quality
Quality is built into the process, from incoming materials to final shipment, with checks matched to your project requirements.
Incoming Material Inspection
Silicone raw materials and incoming inserts are checked against specifications before production.
In-Process Inspection
Critical dimensions and process parameters are monitored during molding and assembly.
Project-Specific Verification
Dimensional, functional and assembly checks are defined per project requirements.
Pre-Shipment Inspection
Finished products are inspected before packing and shipment.
How we work
One team follows your project from first review to repeat production, with clear confirmations at every stage.
Concept & Drawing Review
Send your drawing, sample or concept. We review the application, target quantity and requirements, and confirm feasibility with you before anything is committed.
DFM & Material Selection
Design for Manufacturability (DFM) feedback highlights risks early. Material grade, hardness and process are selected and confirmed with you before tooling is cut.
Tooling & Sampling
Molds are designed and CNC-machined for your project, and first samples are produced for your evaluation.
Validation & Approval
Dimensions, appearance and function are checked against your requirements. You approve samples before mass production begins.
Production & Quality Control
Repeat production runs under controlled process parameters, with in-process checks and final inspection to agreed criteria.
Assembly, Packaging & Delivery
Sub-assembly, marking and export packaging are completed, and your order ships with the documentation your market requires.
