FAQ

Our quality system is built on a foundation of ISO 9001:2015 certification, with our welding and structural fabrication processes adhering to ISO 3834-2 standards. This is not just a document. It's implemented through our Digital Quality Control Platform, where every critical component—from a servo motor to a sealing jaw—is logged with a unique traceability code. This allows us to track performance data back to the specific production batch, ensuring full accountability and enabling statistical process control (SPC) on key dimensions with a Cpk of >1.67 as our standard.
 

We treat our supply chain as an extension of our production. Our supplier qualification process involves a 3-Stage Audit:

• Stage 1: Document Review (Material certifications, RoHS/REACH compliance).

• Stage 2: On-site Technical Audit (Evaluating their CNC capability, heat treatment processes).

• Stage 3: Performance Testing (Running their components in our machines for a 500-hour endurance test).
  Less than 20% of applicants pass this process. Approved suppliers are then continuously rated based on Incoming Quality Yield (IQY) and On-Time Delivery, with underperformers automatically flagged for re-audit.

Quality is manufactured in, not inspected in. Our in-process checks are defined and non-negotiable:

• Dimensional: Critical mating surfaces are measured with laser trackers, holding tolerances of ±0.05mm.

• Electrical: Every control cabinet undergoes a HIPOT (Dielectric Withstand) test at 1500V for 60 seconds.

• Performance: Every machine performs a 72-hour continuous dry-run at 110% of rated speed before shipment. We measure and document vibration levels (must be below 4.5 mm/s RMS) and noise levels (must be below 78 dB).

• All data is recorded in the machine's Digital Birth Certificate.

We employ accelerated life testing (ALT) in our lab to simulate years of wear in months. For example, our sealing jaws undergo a 500,000-cycle fatigue test under thermal cycling from 25°C to 300°C. The main drive system is tested under variable load profiles equivalent to 3 years of continuous operation. The performance decay (e.g., in positioning accuracy) is modeled, and we only approve designs where the decay remains within a 5% threshold after the simulated test period.

Yes, transparency is key. Upon request, we provide certified documentation, including:

• CE Certification: Verifying compliance with EU Machinery Directive 2006/42/EC.

• Electrical Safety Report: Based on EN 60204-1 standards.

• Noise Test Report: From an accredited third-party lab.

• Performance Validation Report: Documenting the results of the pre-shipment dry-run, including actual OEE calculations from the test cycle.

Our Factory Acceptance Test (FAT) is a structured, witness-able event. We follow a pre-agreed FAT Protocol that typically includes:

• Running your specific material to produce a minimum of 1,000 consecutive good bags.

• Verifying production speed against the contract.

• Demonstrating quick changeover procedures.

• Triggering and resolving simulated fault conditions.
  We actively encourage remote participation via live video stream and screen sharing of the HMI/PLC data, allowing you to approve the machine for shipment from your office.

Quality directly determines your operational costs. The equation is simple: Higher Initial Quality = Lower Lifetime Cost.

• Prevents Downtime: A machine with a >96% uptime guarantee (backed by our quality) prevents losses from production stoppages.

• Reduces Scrap: Precision manufacturing means less material waste. We guarantee a scrap rate of <1.5% from machine-related issues.

• Extends Lifespan: A 15-year design life versus a 10-year life effectively reduces your annual depreciation cost by 33%.
  The slightly higher initial investment is amortized by the massive savings in operational and failure costs.

We maintain an On-Time Delivery (OTD) rate of 98.2% over the past 24 months. This is achieved through our Lean and Digital Twin production system. Each machine is virtually assembled and tested in our digital environment first, eliminating engineering conflicts on the shop floor. This allows us to build to order without rushing, ensuring that quality control procedures are never bypassed to meet a deadline. Your schedule is predictable, and your machine's quality is never compromised.

Our Closed-Loop Quality System feeds field data directly back into R&D. Every service intervention, every spare part request, and every performance data point from connected machines is anonymized and analyzed. This has led to tangible improvements, such as the Version 3.0 sealing jaw design, which increased mean time between failures (MTBF) by 30% based on field wear patterns from the previous version. By choosing CHOVYPLAS, you are investing in a product that evolves and improves over time.

For CHOVYPLAS, quality is not just conformance to specifications. It is the guarantee of predictable performance and productivity in your specific environment. Our guarantee extends to your site through our Integrated Commissioning and Validation Program. We don't just install the machine; we work with you to validate that it meets all performance metrics (speed, waste, uptime) using your materials, in your facility, before we consider the project complete. This is our ultimate commitment: your success is the final and only meaningful quality check.
