Plant equipment is too often "fixed only when it breaks", with slow response and no system behind it. The Henghuan group pulls technology, manufacturing and service into one rope, making equipment service a professional discipline.
Industrial robot technology R&D and technical services — the technology source and talent pool of the Henghuan group, continuously supplying leading-edge robotics and automation capability.
Registered in September 2026 and based in the Yilong County E-commerce Industrial Park, building a smart-manufacturing and service base serving north-east Sichuan and the wider south-west market.
A standalone division of the company, focused on whole-life installation and maintenance of plant equipment, led by Engineer Man — senior mechanical & electrical engineer and master technician.
Figures and commitments are the most honest introduction: how many people we field, what tools we carry, how fast we arrive, and which working conditions we dare to take on.
The core of the team is senior mechanical and electrical technicians with decades of shop-floor experience; they start work the moment they arrive - no trainees learning on your equipment.
Vibration meters, infrared thermometers, insulation testers and laser alignment tools travel with the full mechanical and electrical tool sets, so on-site diagnosis never relies on guesswork.
Dusty, humid and corrosive conditions - feed, biomass pellet, building materials, sewage treatment and bio-fertilizer plants - each have dedicated staff for lubrication selection and fault prevention.
After thirty years on site, the reasons factories call us are highly concentrated. Find yourself below and you'll roughly know which module to start with and how much effort it will take.
With orders piling up and deadlines staring, every hour stopped is money. We arrive the same day, first restore production by whatever means, then go back for the root cause; a repair-or-replace conclusion is given on the spot, without leaving you waiting. In the Nanchong area, a technician is typically on site in 1-2 hours.
Most likely the root cause was missed - the broken part was replaced but the trigger that broke it was not. We do failure-mode analysis and treat the triggers together - wear, looseness, lubrication, electrical interference - aiming for one repair that lasts.
Accuracy degradation is usually loose mechanical connections or drifting electrical parameters. We bisect to locate the side at fault - mechanical issues get mechanical correction, electrical issues get parameter adjustment - restoring accuracy to factory standards and process requirements, verified with a standard test piece where necessary.
This is exactly our strong suit. We first survey the electrical circuits on site, complete the mechanical reference data and build the equipment archive, then judge repair, retrofit or replace. At delivery the drawings and archives are handed over together, so future maintenance is never in the dark.
Equipment running with hidden faults and poorly tuned parameters drags energy use and quality down with it. We station on site measuring current, temperature, vibration and cycle times, find the crux with data, adjust parameters and make improvements, pulling the equipment back into its economic operating range.
For equipment that out-of-province suppliers ship into Sichuan, we take on assembly and on-line commissioning, establishing the equipment archive and data baseline from day one of operation. The supplier supports remotely while we execute on site, so your line never waits on someone's schedule.
Not sure which to choose? Tell us your equipment situation and production rhythm and we'll work out which is most cost-effective. Most factories start with one-off service and move to an annual contract once the cooperation runs smoothly.
FIELD · SCHH-2026The six commitments below are hard constraints we place on ourselves - you may hold every job of ours to them.
From arrival to retirement, a machine goes through four stages. Our eight modules cover exactly what each stage requires - we are not someone you remember only when it breaks; someone is watching from start to finish.
Service can begin before the equipment even arrives. For new plants or newly purchased equipment, we take part in building the equipment-management structure, drafting system documents, and setting up the ledger and inspection standards, so that from day one the equipment has someone managing it and an archive behind it. For equipment that out-of-province suppliers ship into Sichuan, we handle assembly and on-line commissioning on the ground and establish the data baseline at start-up, leaving the evidence for later maintenance. Do this stage solidly and you save a great deal of rework later.
The first three months after new equipment starts up are the most easily neglected. Parameters not fully tuned, operators not yet fluent, inspections going through the motions - small troubles accumulate into big problems. We put inspections, lubrication and accuracy calibration on the calendar and coach your crews into the habits, pressing run-in faults to a minimum. Delivery counts only when operators pass assessment - we don't let new equipment run mass production with hidden risks.
FIELD · SCHH-2026
FIELD · SCHH-2026This is the longest stage of an equipment's service life - and the one where vigilance slips most easily. Do preventive maintenance and lubrication management well and faults are nipped in the bud; do them badly and small complaints drag into major overhauls. We run trend monitoring on equipment condition and historical fault data, turning unplanned stoppages into scheduled work inside planned downtime windows, so faults happen at times you can arrange rather than when orders are tightest.
In the later life of equipment, accuracy falls and faults multiply, and repair-or-replace becomes a hard question. We do the economic sums: residual value, downtime losses and retrofit or replacement investment converted onto one table, with three options - repair, retrofit, replace - and their payback periods, for the plant to decide. Old equipment worth refurbishing gets accuracy restoration and automation retrofits for a second round of value at lower investment; equipment due for retirement gets help planning its replacement - we don't let machines soldier on while sick.
Survey — diagnosis — plan — scheduling — execution — acceptance — filing — follow-up: every step has actions, deliverables and oversight.See the methodology and acceptance criteria →
Collect the data on site: current, temperature, vibration, cycle time and downtime records all at once. Facts first, judgement second.
Locate the root cause with the three-step method and the mechanical/electrical split, distinguish intermittent from degradation-type faults, and issue a diagnostic conclusion.
The remedy, schedule, cost and acceptance criteria are explained once and clearly, with a repair/modify/replace economic comparison.
Align the downtime window with the production plan, stage parts and tools in advance, and never let the equipment wait for people.
Clearances, torques and alignment data are recorded item by item and signed off by both parties; no record, no next step.
No-load checks for noise, temperature rise and vibration; load checks on the output curve; accuracy re-measured against factory standards and process requirements.
Drawings, inspection sheets, baseline data and lubrication cards go into the file; handover is only complete once operators have passed their assessment.
Three months of follow-up confirms no recurrence; operating data feeds back into the maintenance strategy so the plan evolves with the equipment.
In many plants, a repair leaves behind nothing but a running machine and a receipt. We are different: every service type has its written deliverables, and a missing item counts as no delivery.
Rooted in Nanchong and Yilong · Serving Sichuan and Chongqing · Reaching across the greater south-west
The five questions asked most often are answered right here on the homepage, so you don't have to search the whole site.
An ordinary repair crew answers "how do we fix this machine"; we answer "why did it fail and how do we keep it from failing again" at the same time. Every service is data-driven work: vibration, temperature and current are measured before anything is touched, and written archives plus preventive recommendations are left at delivery. Behind it all stand thirty years of front-line experience plus the technical backing of the Henghuan system - difficult problems are carried not by one person's experience but by a whole system.
Survey first, plan second, work last. On-site surveys and remote preliminary assessments are free; when equipment work is needed, a written plan states the scope, schedule, cost and acceptance criteria, and work starts only after your confirmation - no mid-job price increases. For emergencies we can repair first to restore production and complete the cost paperwork afterwards per the plan, so the quoting process never delays your line.
Yes. A machine is a machine whatever its size, and a stoppage is a stoppage whatever the plant's size. Fault-finding, maintenance and accuracy calibration for a single machine get the same plan and the same acceptance as anything else. Quite a few annual-contract clients started with one critical machine - once the repair earned their trust, they gradually handed us the whole plant.
Plants throughout Sichuan and in Chongqing, Yunnan and Guizhou are all within our service range: same-day arrival in the Nanchong area, next-day for Chengdu and Chongqing, and usually within 48 hours by schedule for Yunnan and Guizhou. Travel costs are charged at actual cost into the plan quotation, stated in advance and never added afterwards. For equipment that out-of-province suppliers ship into the southwest, the supplier supports remotely while we execute on site - a collaboration model we have long since run smooth.
It is not replacement but division of labour and upgrading. Daily inspections and simple maintenance stay with your plant crews - we teach the standards, forms and methods thoroughly; periodic maintenance, accuracy calibration and difficult faults are ours. During resident and training periods we coach your crews, and the longer the cooperation runs, the stronger your own people become and the less service you need from us - which is exactly what we like to see.
