Compression Molding
Custom VMQ and project-specific silicone parts, including gaskets, rings, diaphragms, bellows, boots and complex profiles.
/ ABOUT SEALS FOR INDUSTRY
Custom silicone manufacturing with an engineering-first approach.
Seals For Industry is the industrial sealing website of Kunshan Fuhongying Electronic Materials Co., Ltd., focused on custom silicone, LSR and overmolded components for equipment manufacturers and industrial buyers.
/ COMPANY PROFILE
From drawing review to repeat production.
Kunshan Fuhongying Electronic Materials Co., Ltd. was established in 2018. The company develops and manufactures custom silicone rubber and liquid silicone rubber components for industrial equipment, electronics, medical equipment, automotive-related programs and other engineered products.
Our work begins with the customer’s interface and service conditions. Engineering review helps clarify material, hardness, compression, tolerance, parting line, undercut, flash, bonding and inspection requirements before the mold is opened.
Projects can progress from design-for-manufacturing review and prototype samples to repeat production, secondary operations, assembly and project-specific inspection. The goal is not simply to mold a part—it is to deliver a component that can be installed, inspected and reordered consistently.

/ MANUFACTURING SUPPORT
Capabilities organized around custom components.
LSR Injection Molding
Liquid silicone components developed for precision, repeatability, complex features and production automation.
Silicone Overmolding
Silicone bonded or mechanically integrated with PC, PA66+GF, metal, stainless steel and other approved substrates.
Tooling & Sampling
Tool design, sample molding, drawing review and feedback before production release.
Secondary Operations
Project-dependent trimming, post-curing, surface treatment, printing, assembly, inspection and packaging.
Quality Planning
Critical-dimension review, first article inspection, visual criteria and requested project documentation.
HOW WE WORK
Make the technical questions visible early.
Early clarification reduces tooling changes, sample delays and production disputes. We encourage buyers and engineers to share the complete assembly context.
01Review the application
Understand media, temperature, pressure, movement, sealing target and failure risk.
02Review manufacturability
Evaluate wall thickness, parting line, undercuts, tolerance, flash and demolding.
03Agree the sample criteria
Define critical dimensions, appearance, fit, test method and approval responsibilities.
04Control production information
Use the approved drawing revision, material, color, packaging and inspection plan.
05Support repeat orders
Maintain clear product identification and communication for ongoing supply.
/ WHY CONTACT US
A practical partner for drawing-based silicone projects.
We are best suited to buyers who need a custom part, engineering discussion, mold development and repeat supply—not a generic retail seal selected only by size.
Application discussion
We ask about the conditions that can change the design or material decision.
Custom manufacturing
Parts are developed around customer drawings, assemblies and production quantities.
RFQ responsiveness
Complete drawing-based inquiries can normally be reviewed for quotation within 24–48 hours.
Global B2B support
English-language project communication, export packaging and international delivery coordination.
