If you need silicone overmolding, insert molding, metal/plastic silicone bonding for 3C electronics, smart wearables, medical devices or new energy parts, have you ever encountered finished products peeling off, delaminating, cracking, or failing adhesion tests after short use?
Many engineers and procurement buyers waste time and mold cost on unprofessional overmolding suppliers. They end up facing bad bonding strength, easy separation, unstable batch quality, and unable to pass high and low temperature aging tests. Why waste money and time on repeated rework when you can cooperate with a professional silicone overmolding manufacturer directly?
で リヤ・シリコーン（www.lyasilicone.com）, we specialize in custom silicone overmolding & insert molding—silicone over metal, silicone over plastic, LSR liquid silicone overmolding and dual-color silicone integration molding. We solve all peeling and delamination problems from design, material selection to mold making. Could we be your long-term reliable overmolding partner?
Can Ordinary Silicone Factories Guarantee Strong Overmolding Adhesion?
Do you think any common silicone factory can do stable silicone overmolding bonding perfectly? The answer is definitely no.
Silicone overmolding is not simply wrapping silicone on metal or plastic. It requires strict control of base material selection, surface treatment, silicone formula, molding temperature and pressure. Unprofessional factories often have these fatal problems:
- Silicone and substrate easy to peel off by hand
- Delamination after high and low temperature cycle test
- Cracking and warping at the overmolding junction
- Bubbles and shrinkage marks on the overmolding surface
Will ordinary factories master professional surface activation treatment for metal and plastic?
Can they match the exclusive silicone formula for different substrates to enhance adhesion?
Do they have aging test equipment to verify long-term bonding stability?
Why take risks with unstable overmolding quality when リヤ・シリコーン has mature overmolding technology and stable bonding solution?
Are You Still Wasting Cost on Overmolding Design & Mold Failure?
Have you ever invested in overmolding mold development, only to find unreasonable structural design leading to demolding difficulty, material filling deficiency and serious delamination?
Most buyers only provide simple drawings and ignore overmolding DFM design analysis. Unreasonable wall thickness, improper glue inlet position, lack of anti-slip and locking structure will cause mold modification, sample rework, delayed project progress and invisible cost loss.
Do you really want to bear extra losses caused by unprofessional overmolding design?
LYA Silicone professional engineering team provides free DFM overmolding design review for all projects. We optimize locking structure, wall thickness, glue inlet layout and demolding angle in advance, avoid peeling and delamination fundamentally, reduce mold modification rate and save your time and mold cost. Why not let professional engineers control every detail for you?
Can Your Supplier Do Both Solid Silicone & LSR Overmolding?
Do your current suppliers only support ordinary solid silicone overmolding, unable to meet your demand for high-precision LSR liquid silicone overmolding?
Different application scenarios need different overmolding processes:
- Solid silicone overmolding: Suitable for conventional protective parts, anti-slip grips, daily electronic accessories, cost-effective
- LSR liquid silicone overmolding: For high-end medical devices, smart watch structural parts, 3C precision seals, with high transparency, no odor, high precision and anti-aging
Many factories only have single process capability, limiting your product upgrading and market layout. Are you willing to be restricted by your supplier’s technical capacity?
LYA Silicone supports solid silicone overmolding and LSR liquid silicone overmolding at the same time. We match the most suitable process and material formula according to your product usage scenario, hardness requirement and quality standard, perfectly covering medical, 3C, smart wearable and new energy overmolding needs.
Are You Still Cooperating With Middlemen for Silicone Overmolding?
Are you still looking for silicone overmolding service through trading middlemen, facing price markup, opaque production progress and no after-sales guarantee for peeling problems?
Cooperating with middlemen means you cannot confirm factory strength in person, cannot track mold and production progress in real time, and once overmolding peeling quality problems occur, middlemen can only pass the buck and cannot solve the root cause. Why let middlemen earn the difference while you lose control of quality and delivery?
LYA Silicone is a direct Shenzhen manufacturer with self-owned mold workshop, overmolding injection molding production line and professional aging testing laboratory. No middlemen, no hidden markup. We provide real-time production photos, videos and quality test reports for every overmolding order, letting you control the whole project clearly.
