WZ-3800 Automatic PCB Horizontal Insertion Machine
What This Listing States
This machine seats through-hole parts into boards and is sold under the Wenzhan brand as the WZ-3800. The stated fields give it 20 feeders, a board window running from 50x50mm to 450x450mm, a 220±10% supply at 50/60Hz drawing 2kW, wooden case packing and carriage by DHL, UPS or FedEx as your order requires. The description area carries a second set of figures that the fields do not repeat — how far the station count can be extended, an upper insertion rate, the directions parts can be seated in, dual part detection and a jumper wire feeder. Everything below is quoted as the listing gives it, with the qualifiers the listing attaches to it.

Performance And Station Notes
- Station count — the description reads "Expandable from 20 stations", so 20 is the starting figure the page gives and the arrangement can be built out from there, not a ceiling stated here.
- Speed — the page quotes "Speeds up to 20,000/hour". That is an upper figure as the listing prints it, with no condition attached on the page; it is not a rate we state as applying at all times.
- Insertion directions — "Insertion Directions: 0°,90°,180°,270°", the four angles named on the page.
- Dual part detection — the listing words this as "two parts in same chain slot"; the mechanism behind it is not described on the page and none is described here.
- Jumper wire feeder — supported, as the description states; the sizes that suit it are not named.
- Low maintenance feeder technology — the description's own wording for the feeder arrangement; no service interval or life figure comes with it.
Advantages listed on this page
Below the figures the page prints an advantages list it attributes to automatic plug-in equipment: greater installation density, better resistance to vibration, improved characteristics, higher labour efficiency and lower production cost. These are the page's statements, reproduced as such. No measurements or guarantees are attached to them here, and they are not offered as a promise of what the machine will return for your operation.
Where Insertion Sits In The Line
Through-hole seating is a stage of its own, between the preparation that precedes it and the soldering that follows. On a mixed board, the surface-mount side runs as a separate sequence and the two processes meet at the soldering stage, where the joints on the inserted parts are finished. If you are working out whether the WZ-3800 belongs before or after a station you already have, send the sequence you run and the board it carries, and the position can be confirmed against it. The soldering equipment for the following stage lives on a separate listing of its own.
What The Page Leaves Open
- Lead pitch, component families and the sizes the machine accepts are not given in the fields or the description.
- Axis count, air requirement, machine weight and overall dimensions appear nowhere on the page.
- First-pass figures, service intervals and output beyond the quoted upper rate are not stated.
- Measured placement performance is not published, and no order-quantity or after-sales term is carried by the listing.
- No condition field appears on this page, so no state is claimed for the unit.
- No approval marks are listed.

Buyer Questions On This Machine
Q1: What is the WZ-3800?
A: An automatic insertion machine that seats through-hole parts into PCBs, listed under the Wenzhan brand.
Q2: How many feeders does it have, and can that be built out?
A: The fields state 20, and the description words the count as expandable from there.
Q3: What speed does the listing quote?
A: An upper figure of 20,000/hour, printed with "up to" — one of the advantages of automatic plug-in equipment. The conditions it applies under are not given, so ask before you rely on it.
Q4: Which angles can parts be inserted at?
A: Four, as the page lists them: 0, 90, 180 and 270 degrees.
Q5: What does dual part detection refer to?
A: The description words it as two parts in the same chain slot; how the machine handles them is not set out on the page.
Q6: Which board sizes fit?
A: The stated window runs from 50x50mm to 450x450mm.
Q7: What supply does the machine take?
A: 220±10% at 50/60Hz, and the draw is 2kW — that is how the fields carry it.
Q8: Where would it sit in a line?
A: Ahead of the soldering stage — the inserted joints are finished after this step. Send your sequence and the position can be checked against it.
Q9: Does the listing state a unit state, an after-sales term or a dispatch time?
A: None of those three is stated here. Send the question and an answer for the unit you have in mind follows.
Q10: How does it travel?
A: It leaves crated in a wooden case, and the three carriers the listing names are DHL, UPS and FedEx — routing follows what your order sets out.
Working With WEN ZHAN
For a machine that seats parts, what matters most happens before anything is ordered. More than twenty years of SMT and dip equipment work sit behind WEN ZHAN Technology, and the same steps run on every enquiry: tell us the board and the part count you expect, and the WZ-3800 build is checked against both, pictures of the actual machine reach you before it is crated, and spares and support stay available as your production grows.
- Company: WEN ZHAN Technology
- Tel / WhatsApp: +86 18823383970
- E-mail: wenzhanhucai@163.com
Send the board you run and the parts going into it — the WZ-3800 station arrangement and carriage for your line can then be confirmed.
