Manufacturing Capability
Four connected disciplines under one roof in Longgang, Shenzhen: mold making, overmolding, cable assembly and electrical validation.
Every capability below sits in one building in Longgang, Shenzhen, and answers to one project owner. That is the whole argument: when the mold, the overmold tool, the assembly line and the test bench are the same team, the quote you get is one we can hold. Use this page as a map — each section covers one discipline, and the last one walks through what a first order actually looks like.
One assembly definition, viewed from four angles.
We run four connected disciplines in the same facility: mold making, overmolding, cable assembly and electrical validation. Most suppliers subcontract at least one of them. We keep them together because they are not four separate problems — they are one assembly definition viewed from four angles.
When the tool room and the cable line sit in the same building, a change to strain-relief geometry is a conversation, not a purchase order.
Four capabilities, one accountable party.
Overmold tools, insert holders and assembly fixtures designed and machined in-house. 100 sets built to date.

Why in-house tooling changes the quote.
- Fewer handoffs
- The engineer who reviews your DFM question is in the same room as the person who cuts the mold.
- Faster iteration
- A T1 sample that needs a gate change or a longer strain-relief body is a same-building adjustment, not a three-week external re-quote.
- One accountable party
- Fit, pinout, seal and finish problems have a single owner instead of a blame triangle between mold shop, assembler and trading company.
- Your geometry stays yours
- Tool ownership, drawings and process parameters are documented and held under your project reference. Tools are retained and maintained free of charge for 36 months after last production.

How a first order runs, start to finish
Two numbers matter when you are planning a build: samples in three working days, production in fourteen. If the part needs new tooling, add ten more before the first article comes off the tool.
1. Drawing, sample or BOM
Send whichever you have. If all you have is a sample, we measure the interface, map the pinout and return a drawing for approval before anything is quoted.
2. Approval sample
Three working days for most assemblies. You check the sample against your own fixture before we book production time.
3. Tooling, if it is needed
Overmold and insert-mold tools are cut in our own mold shop. New tooling adds about ten working days, and the tool is yours.
4. Production and release
Fourteen working days from approved sample, with electrical verification on every unit before it is packed. See what we test.
Production starts at 500 pcs per part number, and we build from 32 to 12 AWG. If your volume or gauge sits outside that, ask anyway — we will tell you quickly whether it is a fit.
Have a drawing, a sample or an unresolved interface problem?
Send the connector type, cable spec, environment and target quantity. We will come back with the engineering questions that actually change the build — not a generic price list.
Manufacturing: FAQ
How quickly can you quote?
Most enquiries get a number back within one working day once the interface is clear — a drawing, a BOM or one sample is enough to start. Anything that needs new tooling takes longer, because the tool design has to be priced with it.
Do you hold stock of standard cables?
We are a build-to-order shop, so holding stock is not the business. We do run standard specifications — Cat5e, Cat6 and Cat6A patch cords, M8 and M12 cordsets — when a program needs them alongside a custom assembly.
What is the minimum order?
500 pcs per part number for production runs, while prototypes and samples are built from 1 to 50 pcs. Below the production figure, the setup and tooling cost per piece stops making sense for either of us.
Do you build to IPC/WHMA-A-620?
We work to IPC/WHMA-A-620 Class 3 as the internal criteria for crimp and assembly workmanship, and the process runs under an ISO 9001 quality system. We state it as the standard we build to rather than a certificate we hand you.
