01 / Our company
A practical partner
for complex parts.
Founded in 2017, JY Pretech Co., Limited brings together tooling, molding and engineering support in Zhongshan, Guangdong. Our work spans high-heat plastics, two-shot molding, liquid silicone and metal manufacturing.
We support product development at different stages: early material trials, rapid and bridge tooling, low-volume manufacturing and production programs. Part requirements—not a one-size-fits-all process—guide the route we recommend.
In-house tooling and injection molding are complemented by additional manufacturing resources where a project calls for them. That gives our team a practical way to coordinate the next step around your design.
Our focus: make the path from a drawing to a finished part clearer.
02 / Inside JY Pretech
The place where
engineering becomes tangible.
Take a closer look at the tooling, molding and inspection environments behind our work.
The tooling workshop
From precision machining
to the first mold trial.
Our tooling workshop combines machining, electrode and mold-making operations with fitting and polishing to support the development of your tool.
CNC machining
EDM
Wire cutting
Mirror EDM
Mold fitting
Polishing
Injection molding
80–650 ton machines, including precision and two-shot injection equipment.
Two-shot production
Dedicated two-shot capability for compatible material and color combinations.
Liquid silicone molding
A controlled-environment workshop for LSR molding projects.
Workshop imagery reflects JY Pretech operations. Machine configurations and availability are confirmed for each project.
05 / Material know-how
Material expertise is
Explore the materials we work with
Material expertise is
part of the design.
Choosing a polymer is not only about a datasheet. Temperature, dimensional stability, chemical exposure, wear and appearance all influence tooling and processing decisions. Our team helps translate those requirements into a practical material and manufacturing route.
01
High-performance thermoplastics
PEEK, PEI (ULTEM), PPSU, PPS, PPA and related engineering resins for parts with demanding mechanical or thermal requirements.
02
Two-shot & hard-soft combinations
PC, ABS, PA and TPE combinations are evaluated for interface geometry, bonding behaviour, functional grip and finish.
03
Liquid silicone & elastomers
LSR, insert molding and overmolding can support flexible seals, interfaces and components with fine geometric details.
APPLICATION MATERIALS
Built around the requirements of the part.
High-heat molded part examples
03 / The parts behind the process
Different applications.
The same attention to detail.
Our portfolio brings together flexible silicone, multi-material assemblies and technical plastic components for a range of product needs.
Form meets flexibility.
LSR parts and overmolded components, with material grade and application requirements reviewed at the start.
Designed to come together.
Housings, panels and functional components supported by tooling, molding and secondary operations.
Material matters.
High-performance polymers selected and processed around the component’s operating conditions.
06 / Selected project experience
Real parts.

Different challenges.
Every part creates its own decisions about materials, mold construction and repeatable production. Explore examples already shared by JY Pretech on its website.
TWO-SHOT MOLDING
Multi-material bike seat
A bicycle seat program called for rigid and soft polymers to work together while addressing appearance, interface bonding and assembly complexity. The published project explores design adjustments and a coordinated two-shot process.
Engineering focus
Material compatibility, bond area and repeatable production
Read the case study
LIQUID SILICONE
Silicone face-mask components
A flexible silicone component developed for a face-mask application. The project illustrates why part geometry, tooling and material suitability must be reviewed together.
Engineering focus
Flexible geometry and appropriate LSR processing
Read the case study
HIGH-HEAT POLYMERS
PEI for technical applications
JY Pretech also documents the use of PEI in medical applications, where material selection is informed by heat resistance, stability and the intended operating environment.
Engineering focus
Polymer grade selection and mold/process review
Read the case study
Images are selected examples from the company portfolio. Each case relates to a specific project; suitability and performance for a new part require a separate engineering review.
01
Start with the part.
Understand the geometry, material, function and critical requirements before recommending a manufacturing route.
02
Keep the dialogue clear.
Make technical questions, changes and project decisions part of an open engineering conversation.
03
Plan the next stage.
Consider tooling, finishing and production needs together—not only the first samples.

A few questions
A few questions
before we begin.
Every quotation starts with a real part and a set of requirements. These answers explain how we approach common sourcing questions.
Talk to our team ↗Can you support prototypes and smaller batches?
Yes. Rapid and bridge tooling, low-volume injection molding and selected no-MOQ options can be discussed. Suitability, unit pricing and lead times depend on the part, process and project volume.
What materials can you work with?
Our material portfolio includes high-temperature grades such as PEEK, PEI and PPSU, standard engineering thermoplastics, TPE combinations and liquid silicone. We confirm the exact grade and required documentation during technical review.
Do you make tooling for overseas production?
JY Pretech supports export tooling and mold components. Supply specifications can reference DME, HASCO and other requested standards, together with the customer’s injection machine and toolroom requirements.
What should we include in our initial enquiry?
Send a STEP/IGS model if available, a dimensioned 2D drawing, material or application requirements, expected quantities, critical tolerances and target schedule. We can then identify the questions that need discussion before quoting.
