About YHIOT
Dongguan Yuanhong Zhizao Technology Co., Ltd. is a technology-driven manufacturer built on silicone compound development, dissimilar-material bonding and precision silicone molding. We focus on silicone integrated with electronics and cover the full chain: material development, structural design, tool development, process definition, reliability verification and volume delivery.
A manufacturing direction focused on overmolding and composite molding
YHIOT is based in Dalingshan Town, Dongguan, working on precision overmolding and dissimilar-material composite molding of silicone with metal, plastic and PCBA. We do not compete on low-price volume products; the effort goes into the harder problems of this industry — delamination, bond failure, missed performance targets, limited appearance processes, unstable volume production and insufficient weathering.
Our customers are mainly smart hardware, consumer electronics, medical protection, wearables, industrial security and cross-border brand owners. We also provide technical services to the industry: process improvement, training and supply-chain management.
These parts rarely succeed or fail because of the silicone itself; it happens at the interface — how the insert is fixed, how far the silicone covers, where the parting line runs, whether the gate position displaces a component. That is why the early project time goes into structural assessment: the possible failure points are put on the table before tooling and sampling are discussed.
On cooperation, we quote from drawings or samples. If there is no drawing yet and only an idea, we start with requirement review. A project can run from design, process route definition, sampling, process and cost optimisation all the way to production tooling and volume delivery under one supplier, which removes the drift that comes from handing information between parties — or you can join at a single stage: sampling verification only from your own tool, or material selection and surface finishing advice only.
Alongside metal inserts and plastic composites, one product family carries electronics: wristbands, rings and labels made by overmolding silicone onto RFID chips, and precision liquid encapsulation of outdoor LED displays. Both follow the same structural logic.
Position and principles
Technology as the base, quality as the reputation, service as the market
Research standards control the source, precision processes protect performance, and full-chain service solves customer problems. We do not compete on homogenised low prices; technical accumulation is the core competence.
Operating principle
Decide in the early project stage and keep risk away from volume production. Every delivery is backed by a repeatable process and by data.
People
Senior people make senior products. Core roles are filled through strict entry standards and above-market pay, so a seasoned team can support demanding processes and demanding products.

Core strengths
From making parts to defining the option
A conventional silicone factory mainly molds parts. Our capability extends to compound modification, interface activation, dissimilar-material bonding and ageing verification, so material and process can be customised to the operating conditions and certification standards.
Technical depth
A complete technical system covering compound modification, surface activation, nano bonding, composite molding, precision molding and ageing verification — aimed at the root of delamination, bond loss, cracking, poor weathering and short service life.
Closed-loop service
Structural design, compound development, colour and mixed compound customisation, tool and fixture development, molding and surface finishing, sampling and testing, volume optimisation, assembly, quality and certification, supply-chain and logistics management.
R&D and verification
In-house laboratory and reliability testing covering composition analysis, mechanical testing, environmental ageing, electrical insulation, wear life and precision dimension; new products, processes and formulas are verified with data.
Team
Core technical roles are filled to high entry and capability standards, with teams able to develop formulas, optimise tool structures, correct difficult processes and stabilise volume production.
Technical support as well as production
Beyond product customisation we provide technical services, process optimisation, compliance and certification support, IP support, training and supply-chain management — serving both brand owners and fellow factories upgrading their processes.
Focused on difficult customisation
Resources are concentrated on silicone plus electronics, precision overmolding, special processes and difficult volume problems — for projects with clear reliability and appearance standards that still lack a workable plan.
How we work
Four things we turn a project into
Overmolding customisation is rarely right the first time. Whether a plan can be executed depends on how clearly each step is confirmed.
Structure first
Judge whether the overmold structure holds up and whether the load path and assembly are sound, then discuss material, hardness and colour — so nothing collapses after the option is fixed.
Material matched to process
Molding route and insert material constrain each other. The proposal states the reason for each choice and the parameters the customer must confirm.
Sampling as verification
Sampling is not only about appearance: it includes trial assembly and dimension checks, and its result becomes the basis of the volume process window.
Information kept in sync
Assessment results, open items and changes are confirmed in writing, which removes the drift caused by drawing revisions and verbal descriptions.
Cross-industry cooperation
Not only silicone — we understand the neighbouring industries
An overmolded silicone part is usually one component in a finished device, and how it is made depends on how the parts around it are machined and assembled. We have cooperation experience in electronics, batteries, electromagnetic components and plastic or metal hardware, know their processing and surface finishing methods, and bring those constraints into the overmold plan early to avoid rework across processes.
Electronics
- Understanding of PCBA, component and solder-joint protection needs
- Knowing which components the gate must avoid and which areas cannot be pressed
- Matching the assembly and reliability acceptance criteria of electronic parts
Battery
- Familiar with the structure and assembly constraints of cells and packs
- Insulation, sealing and protection requirements considered in the same plan
- Interfaces matched with upstream and downstream processes
Electromagnetic
- Coverage thickness and position of antennas, coils and sensing elements affect performance
- Coverage method and signal behaviour considered together
- Functional verification arranged at the sampling stage
Plastic and metal
- Familiar with molding and machining of plastic and metal parts
- Aware of how common surface finishes affect the silicone bond
- Overmold tolerances and process sequence aligned with the neighbouring stages
The practical value of this cooperation is fewer detours: which process must come first, which surface condition must not be touched, which dimension cannot be compensated by silicone alone. Settling these at the proposal stage costs less than correcting them at sampling or in volume. The related processes are covered under the capability pages; the technical roles behind them are described in the team page.
Scope of service
From an idea to volume delivery
Many projects start from a sketch, an idea or a single sample. We can cover the whole path from concept to volume production — each stage can be bought on its own or run end to end.
