Who Makes HyHaven Actuators? Inside the Wenzhou Manufacturer Behind This Store

Most product pages on the internet are written to sound big. This one is written so you can check it.

HyHaven is the brand of Wenzhou Jianshun Electrical Co., Ltd., a manufacturer based in Zeya Town, in the Ouhai District of Wenzhou, Zhejiang, China. The store you are reading — hyhavenstore.com — is where we sell direct. There is no trading company in between and no distributor marking things up: the company that makes the products is the company that answers the email when something goes wrong. Our address is public — No.13 Dayuan Road, Zeya Town, Ouhai District, Wenzhou, Zhejiang, China — because it is also the address on the return label if you ever need one.

This article is not a company brochure. It is a short guide to verifying us: where the specifications on this site come from, what you can download and check before you order, what testing actually happens in the building, and what happens after you place an order.

One Manufacturer, Two Product Lines

Jianshun runs two product lines out of the same Wenzhou operation, and it helps to keep them separate, because they are sold and checked differently.

The actuator line is the one most readers of this blog know: the U-series actuators from the 900 N U1 up to the 12,000 N U7, the wired and wireless controller kits that drive them, and the HH-series worm gear motors. The fastener line is a different kind of business — nothing is off the shelf; every part starts from a customer's drawing. They share a brand and an owner. They do not share specifications, and this article will not borrow credibility from one to dress up the other.

Check Our Numbers Yourself: Full-Load Data, in the Open

The easiest way for an actuator seller to look good is to publish only no-load numbers. A motor spinning with nothing attached is fast and draws little current; neither figure tells you what happens when the actuator is actually pushing your hatch, lift, or machine cover. So on this store, every actuator product page carries a Full Specifications section that includes the loaded figures — full-load current and full-load speed — next to the no-load ones.

Two examples, so you can see the pattern before you click anything:

• The U3 6000 N actuator lists a full-load current of 8.5 A at 12 V and 3.8 A at 24 V. That is the number you size your power supply with, and it is printed on the page rather than buried in a PDF you have to request.
• The U7, our 12,000 N heavy-duty model, lists 20 A at 12 V and 10.5 A at 24 V at full load. Heavy actuators are hungry; we would rather you know that before ordering than after your power supply shuts down.

Why does the loaded figure matter enough to headline a section? Because almost every sizing decision downstream depends on it. Your power supply, your wiring, and your controller all have to survive the current the actuator draws at full load — not the gentler figure it draws while moving nothing. Our power supply guide walks through that sizing step by step using the same full-load numbers printed on the product pages; the guide and the pages cannot quietly disagree, because both point at the same table.

If you want the documents rather than the web page, the U1, U2, U3, U11, and U6 product pages each offer a downloadable Datasheet PDF. The U7 page offers a dimension drawing download instead — that is what exists for that model today, and the page labels it as such rather than calling it something it is not.

Certification You Can Look Up

The U-series actuators named above are covered by an Attestation of Conformity issued by UDEM International Certification, covering the EU Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). Certificate number M.2023.206.C84513, registered in April 2023 and valid until 23 April 2028; its validity can be checked with the issuing body. The certificate covers the JS-TGZ-U model series — sold on this store as the U1, U2, U3, U5, U6, U11, and U7 — and the full document is published on our certifications page, so you can read exactly what it covers instead of taking a logo's word for it.

Scope matters more than the badge: the worm gear motors and the controller kits are not listed on that certificate, and we make no CE claim for them. One document, one defined set of models — that is the whole claim.

This is the standard we hold the whole store to: if a figure is on a page, it is a figure we can stand behind; if we have not verified a figure, the page leaves it out instead of rounding it into existence. Several of the guides on this blog exist precisely because a specification was missing or unclear — the fix was always to verify the figure against the factory documentation, publish it, and link to it, in that order.

Testing We Can Point To: The Fastener Line's Lab

The clearest view of how this company treats quality is the fastener line, because made-to-drawing parts live or die on inspection. Every custom fastener order is checked in-house across six items: material composition, metallographic structure, hardness, dimensions, profile, and surface roughness. Dimensional tolerance on machined work is held to ±0.05 mm, across a cold-heading range of M5–M24 and a machining range of M8–M64. Test reports are available with your order — not as a marketing claim, but as paperwork that ships with the parts.

We wrote up exactly what each of those six tests checks, and what a failing result looks like, in our guide to fastener inspection. If you are evaluating us as a fastener supplier, that article plus the custom fasteners page will tell you more than any slogan: the process is drawing review, quotation, sample approval, then production with inspection before shipment.

One honesty note, because it matters: that lab story belongs to the fastener line. We are not going to imply that actuator testing is something it is not. What the actuator line offers instead is published full-load data and downloadable datasheets, as above — a different kind of evidence for a different kind of product.

What Happens After You Order

Trust is also logistics, so here is the unglamorous part, in writing:

• Shipping. Orders ship from Wenzhou. Preparation takes 1–2 business days, and air delivery takes 5–8 business days. Shipping is a flat $10, and free on orders of $59 or more.
• Warranty. Every actuator we sell carries a 12-month warranty from delivery. If a unit fails in normal use because of a defect in materials or workmanship, email support@hyhavenstore.com with your order number and a short description of the problem — a photo or a brief video helps us diagnose it quickly — and we will take it from there.
• Returns. You have 30 days from delivery. If you simply changed your mind, you cover the international return shipping; we do not charge a restocking fee. Defective or wrong items are handled differently — contact us first and we will sort it out.
• Contact. Email support@hyhavenstore.com or WhatsApp +86 139 5881 4345. The FAQ page collects the questions buyers ask most, including payment and shipping details.

None of this is exotic. It is the baseline a buyer should be able to read before paying, stated in one place so you do not have to dig for it at checkout.

What You Won't Find on This Site

A short list, because absence is also information. You will not find a wall of certification logos: the one certificate we hold — the CE attestation covering the U-series actuators listed on it — is published in full on our certifications page, number, scope, and expiry date included, and products it does not list carry no certification claim at all. You will not find customer case studies or order volumes quoted as social proof. And you will not find a founding year, a headcount, or a factory-size figure doing rhetorical work — if a number about this company matters to your decision and it is not on this page, ask us at support@hyhavenstore.com and we will answer directly rather than decorate.

What you will find is a manufacturer you can identify, specifications you can download, loaded performance figures printed where you can see them, an inspection process described test by test, and return terms written down before you buy. For most buyers comparing actuators or sourcing custom fasteners, that is the evidence that actually predicts how an order will go.

Start with the product itself — the U1 page is a good example of the Full Specifications format used across the range — or, if you are sourcing parts, send us a drawing through the custom fasteners page. Either way, check the numbers first. That is what they are published for.
