Company story

Eighteen years building the same discipline.

Wetop Silicone opened in 2008 as a small Dongguan workshop with a single compression press. The customers were housewares OEM buyers who needed dedicated tooling on a tight timeline — the same brief that drives most programs on our floor today.

The factory has grown, but the operating principle has not. Every RFP reaches the engineering team before sales. Every mold is cut in-house. Every batch is post-cured and lot-traced. Nothing is subcontracted, and no production step happens somewhere the customer can’t audit.

The result is a factory that is deliberately mid-sized: large enough to run Costco-volume programs, small enough that a first-article failure reaches the engineering desk the same day it happens.

The discipline

How a program moves from CAD to carton.

Six workstations under one roof. Nothing subcontracted, nothing offshored twice. Every step happens where the engineer who wrote your reply can walk over and check it.

Audit welcome

One customer audit per month. Yours can be next.

Third-party audit reports are a one-time snapshot. Customer audits are where buyers actually see how a supplier operates. In-person audits at the Dongguan facility on one week’s notice; virtual walkthroughs within 24 hours of request. Roughly one customer audit lands on our floor per month.

FAQ · the factory

Five questions procurement teams ask before the audit.

  • Are you a factory or a trading company?

    Founder-led factory — 60 employees on a 7,500 m² floor in Dongguan. We own the molds, the compression presses, the post-cure ovens, the QC stations, and the production logs. We do not subcontract any production step that touches your geometry. Customer audits walk through the building where their parts are molded.

  • Where exactly is Wetop Silicone located?

    Dongguan, Guangdong Province — 90 minutes from Yantian Port, 60 minutes from Shekou Port, 2 hours from Hong Kong International Airport, and 1 hour from central Shenzhen. The location is intentional: the highest-density silicone-manufacturing belt in the world, with strong supplier proximity for stainless-steel rod, master-batch color, and food-grade silicone gum.

  • Can we audit your factory before placing the first order?

    Yes. In-person audits at the Dongguan facility can be scheduled with one week's notice. Virtual factory tours via video call are available within 24 hours of request — we walk through the press floor, mold storage, QC stations, post-cure ovens, and packaging line. We host roughly one customer audit per month and treat audits as the primary trust-building step, not a generic third-party report substitute.

  • What is your monthly production capacity?

    Capacity is SKU-dependent. Our compression line runs multi-shift for higher-volume programs and can scale into the hundreds of thousands of pieces per SKU per month; the LSR injection line handles precision programs in parallel. Actual capacity for your program depends on cycle time, cavity count, and post-cure schedule — send a brief and an engineer will scope it.

  • You don't have an SGS or Disney FAMA audit — does that matter?

    For most brand customers, the brand or retailer conducts their own factory audit — which is more rigorous than a generic third-party report. We provide ISO 9001 documentation, per-batch FDA 21 CFR 177.2600 and LFGB §30/31 test reports from accredited labs, full batch traceability, and a customer audit on demand. If your program requires a Disney FAMA, Sedex, or similar audit, we will pursue it — that is a customer-specific cost built into the program quote.

Send a brief, get an engineer's reply in one business day.

Every Wetop program is custom-tooled to a customer’s spec. To scope your program we need your CAD file (STEP · IGES · DWG) or a written brief, your target volume, and any compliance requirements (FDA, LFGB, EN 14350, RoHS, and so on). We reply with a mold cost estimate, price brackets at MOQ 500 / 1,000 / 5,000, and 2–4 engineering questions about edge cases in your spec.

Send your brief

Describe your program and attach CAD or reference files. An engineer replies within one business day.
