After-sales
Technical service and spare parts for bag closers and baggers
We install, adjust and maintain sewing heads, sewing systems, portable bag closers and baggers of the brands we represent, with original spare parts and trained staff in Costa Rica.
What we do
Services that keep your line running
Installation and start-up
We install the equipment on your line, level it with the conveyor, adjust sewing height, tension and stitch, and leave it producing.
Preventive maintenance
Inspection, lubrication, cleaning and replacement of wear parts before they fail, to avoid stoppages in the middle of the season.
Repair and adjustment
Diagnosis and repair of sewing heads, portable bag closers, sewing systems and baggers: skipped stitches, thread breaks, weight drift.
Original spare parts
Loopers, needles, feed dogs, knives, belts and factory parts for Fischbein, Newlong, Megatex (Yaohan), Hamer and TMI, with direct factory orders for special parts.
Operator training
We teach threading, lubrication, stitch adjustment and how to spot common faults, so your equipment runs longer without stopping.
Line expansion
When your production grows, we assess what makes sense: another bag closer, an automatic feeder, a higher-capacity scale or an automatic line.
How to request it
From the report to a running machine

Frequently asked questions
What information do I need to request service or a spare part?+
The make and model of the equipment, the serial number if it is visible on the nameplate, and a description of the problem. A photo of the part or a video of the problem speeds up the diagnosis.
Why use original spare parts?+
An out-of-spec looper or needle causes skipped stitches, thread breaks and head wear. Original parts keep the factory calibration.
How often should preventive maintenance be done?+
It depends on hours of use and the product: in environments with dust, salt or fertilizer it should be done more often. We recommend a frequency after seeing your line.
Do you train our operators?+
Yes. Training covers threading, lubrication, stitch adjustment and detection of common faults, at your facility and on your own equipment.
