Test 11 – gdy nowe rozwiązania naprawdę spotykają się z linią produkcyjną

Wyobraź sobie halę produkcyjną w poniedziałek o 5:30 rano. Linia do pakowania wstaje razem z pierwszą zmianą. Na taśmę wjeżdżają tacki z mięsem mielonym – produkt wrażliwy, wymagający idealnej szczelności i stabilnej atmosfery modyfikowanej (MAP).

Do tej pory co kilka dni ktoś zgłaszał ten sam problem: „Za dużo odrzutów przez mikroprzecieki”, „termin przydatności nie trzyma deklaracji”, „za wysokie zużycie folii”. Wszystko działa – ale nie działa optymalnie.

To właśnie w takich momentach w PAK Toruń wchodzi na scenę coś, co nazywamy wewnętrznie „Test 11” – czyli etap, na którym nowe rozwiązania są weryfikowane nie w laboratorium, ale w realnej, często bezlitosnej praktyce produkcyjnej.

Od laboratorium do taśmy – po co nam „Test 11”?

Nowa folia barierowa, nowy laminat, nowa konfiguracja MAP – wszystko wygląda obiecująco na papierze. Mamy dane: - wysoki poziom bariery dla tlenu i pary wodnej, - świetne zachowanie w testach zgrzewu, - potwierdzoną zgodność z wymaganiami kontaktu z żywnością, - obietnicę niższego zużycia materiału lub mniejszej grubości folii.

Tylko że produkcja spożywcza to nie sterylne laboratorium. To: - wahania temperatury w hali, - różnice w wilgotności, - zmęczone formierki i zgrzewarki po kilku latach pracy, - realne tempo linii, gdzie każda sekunda cyklu ma znaczenie.

„Test 11” to moment, w którym sprawdzamy, czy to, co działa idealnie w teorii, naprawdę sprawdza się przy wielotysięcznych seriach dla mięsa, nabiału, pieczywa czy dań gotowych. I dopiero wtedy mówimy, że rozwiązanie jest gotowe dla przemysłu.

Case z produkcji: mięso w MAP, mniej plastiku, zero kompromisów

Jeden z ostatnich projektów dotyczył producenta mięsa pakowanego w atmosferze modyfikowanej. Wytyczne były jasne: - wydłużyć trwałość o minimum 2 dni, - zmniejszyć ilość odrzutów z powodu nieszczelności, - obniżyć zużycie plastiku na opakowanie, - nie modyfikować radykalnie istniejącej linii (maksimum – drobne regulacje parametrów).

Brzmi jak lista życzeń? Dla nas – jak typowy brief.

Po stronie technologicznej pracowaliśmy nad: - doborem folii górnej o zwiększonej barierowości przy jednoczesnym obniżeniu grubości, - optymalizacją warstwy zgrzewalnej tak, aby tolerowała drobne zanieczyszczenia na rancie tacki (np. śladowe ilości tłuszczu), - dopasowaniem parametrów zgrzewu do konkretnej zgrzewarki klienta: temperatura, czas, docisk, profil chłodzenia.

Właśnie w tym procesie kluczowe okazały się praktyczne wnioski z naszych badań typu Test 11 nowych rozwiązań do pakowania w atmosferze modyfikowanej, gdzie zestawiamy wymagania linii produkcyjnej z właściwościami folii w rzeczywistych warunkach pracy.

Efekt? - Spadek odrzutów z powodu mikroprzecieków o ponad 40%, - wydłużenie deklarowanego terminu przydatności dzięki stabilniejszej barierze MAP, - redukcja zużycia plastiku na jednostkę produktu poprzez zastosowanie cieńszej, ale bardziej zaawansowanej folii barierowej.

To nie jest „magia nowego produktu”. To jest konsekwentne łączenie R&D, znajomości procesu klienta i testów w warunkach zbliżonych do jego codziennej rzeczywistości.

Nowe rozwiązania w praktyce: co realnie zmienia się na linii?

Gdy mówimy o „nowych rozwiązaniach w praktyce produkcyjnej”, nie chodzi tylko o świeży katalog folii czy laminatów. W realu liczy się to, co zauważy operator linii i kierownik produkcji po tygodniu pracy. Najczęściej są to:

Stabilność procesu

Mniej przestojów spowodowanych koniecznością ponownego ustawiania parametrów.

Mniejsza wrażliwość materiału na drobne odchylenia w temperaturze zgrzewu.

Bezpieczeństwo i szczelność opakowań

Pewny zgrzew, który nie puszcza pod naciskiem, w transporcie czy w chłodni.

Stała bariera tlenowa – kluczowa dla mięsa czerwonego, wędlin, dań gotowych.

Trwałość i jakość produktu

Mniej zmian barwy i zapachu przy dłuższym przechowywaniu.

Lepsza ochrona przed utratą wody (mięso), wysychaniem (pieczywo), obsychaniem powierzchni (ser, produkty mleczne).

Ekonomia procesu

Niższe zużycie materiału przy zachowaniu (lub poprawie) bezpieczeństwa.

Lepsza powtarzalność, dzięki której łatwiej planować produkcję i redukować straty.

Dla produkcji oznacza to nie tylko „nową folię”, ale konkretny, mierzalny wpływ na wynik finansowy oraz komfort pracy zespołu na zmianie.

Trendy, które widać z poziomu… zgrzewarki

Nowoczesne opakowania dla branży spożywczej to dziś skrzyżowanie kilku silnych trendów, które spotykają się właśnie na linii pakującej:

Ekologia i redukcja plastiku Klienci oczekują mniejszej masy opakowania, ale bezpieczeństwo żywności nie może na tym ucierpieć. Dlatego rozwijamy folie barierowe o wyższej wydajności – cieńsze, a jednocześnie bardziej „inteligentne” pod względem struktury i funkcji.

Optymalizacja kosztów całego procesu, nie tylko materiału Tania folia, która generuje odrzuty, przestoje i reklamacje, w praktyce staje się najdroższym możliwym wyborem. Nasze testy „w praktyce” są właśnie po to, by koszty liczyć całościowo: materiał + czas + straty + logistyka + reklamacje.

Automatyzacja i integracja z liniami wysokowydajnymi Nowe rozwiązania muszą być kompatybilne z szybkimi termoformierkami, traysealerami, flow-packami. Margines błędu przy 120–200 cyklach na minutę jest bliski zeru – materiały opakowaniowe muszą po prostu nadążyć.

MAP i wyspecjalizowane bariery Od mięsa i drobiu, przez sery, po dania gotowe – każde z tych zastosowań potrzebuje nieco innej kombinacji barierowości, zgrzewalności i odporności mechanicznej. Tu właśnie wchodzi rola producenta, który nie tylko „sprzedaje folię”, ale projektuje rozwiązanie pod konkretny produkt i linię.

Dlaczego „Test 11” jest ważny dla naszych klientów?

Bo to moment, w którym kończy się teoria, a zaczyna praktyka. Z perspektywy producenta żywności oznacza to: - mniej ryzyka przy wdrażaniu nowego materiału, - krótszy czas od testów do stabilnej produkcji, - jasne, policzalne efekty (np. X% mniej odrzutów, Y dni dłuższa trwałość, Z% mniejsza gramatura).

Z perspektywy konsumenta – to po prostu świeższy, bezpieczniejszy produkt w sklepie. Opakowanie, które „działa”, ale nie przykuwa niepotrzebnie uwagi – tak, jak dobre technologie powinny.

Jeśli stoisz teraz przed wyzwaniem: - wymiany obecnych folii na rozwiązania bardziej ekologiczne, - poprawy trwałości produktów bez zwiększania ilości dodatków, - zmniejszenia wskaźnika odrzutów na linii, - przygotowania się do automatyzacji pakowania lub przejścia na MAP,

warto porozmawiać zanim pierwszy metr nowego materiału trafi na Twoją linię.

Skontaktuj się z nami, opowiedz o swojej produkcji, a my zaproponujemy rozwiązanie, które przejdzie nie tylko test w laboratorium, ale przede wszystkim własny „Test 11” – na Twojej hali.

What Is a Dial Indicator?

A dial indicator is a precision measuring instrument used to detect small dimensional deviations, alignment errors, runout, flatness variations, and positional changes in machine tools and fixtures.

The Importance of Surface Measurement in Precision Metal Parts: A Supply Chain Perspective

What Is Surface Measurement?

Surface measurement refers to the process of evaluating the texture, roughness, waviness, and overall surface condition of a manufactured component. In precision manufacturing, surface quality is just as important as dimensional accuracy because it directly affects assembly performance, wear resistance, sealing capability, and product lifespan.

Common surface measurement parameters include:

Ra (Average Roughness)

Rz (Maximum Height Profile)

Surface Flatness

Surface Finish Consistency

For industries such as aerospace, automotive, medical devices, and precision machining, surface measurement is often specified alongside dimensional tolerances.

Why Surface Measurement Matters in Precision Metal Parts

A component may meet dimensional specifications yet still fail in real-world applications if its surface quality is inadequate.

For example, a hydraulic valve spool machined to a tolerance of ±0.01 mm may still experience leakage if the surface roughness exceeds the required Ra 0.4 μm specification.

This is why manufacturers increasingly integrate surface inspection into their quality control systems rather than treating it as a secondary inspection process.

Surface measurement contributes to:

Product reliability

Reduced friction

Improved sealing performance

Longer service life

Lower warranty claims

Surface Quality and Defect Reduction

Industrial distributors and OEM buyers often focus on dimensional accuracy while overlooking surface-related defects.

Common surface defects include:

Tool marks

Burrs

Scratches

Chatter marks

Oxidation spots

Surface waviness

Even minor surface imperfections can lead to assembly problems or premature component failure.

A structured inspection process using calibrated measuring instruments helps identify defects before products enter the supply chain.

What Are Measuring Tools for Tight Tolerance Applications?

Measuring tools for tight tolerance applications are precision instruments used to verify dimensional accuracy in manufacturing environments where even small deviations can affect product performance. Common examples include digital calipers, micrometers, height gauges, and optical measuring systems.

In industries such as aerospace, automotive, mold manufacturing, and precision machining, tolerances often range from ±0.01 mm to ±0.005 mm. Under these conditions, the reliability of measurement tools directly influences product quality, production efficiency, and supply chain stability.

Why Measuring Tool Selection Matters Beyond Quality Control

Many procurement teams focus primarily on unit price when purchasing measuring equipment. However, from a supply chain perspective, the true cost of a measuring tool extends far beyond the purchase price.

Poor measurement repeatability can lead to:

Increased defect rates

Rework and scrap costs

Production downtime

Delayed customer shipments

Higher warranty claims

As a result, measuring tool selection should be viewed as a strategic procurement decision rather than a simple purchasing task.

Defect Rates and Measurement Accuracy

Defect rates remain one of the most important performance indicators in modern manufacturing.

For example, a CNC machining facility producing hydraulic valve components with a tolerance requirement of ±0.01 mm may experience significant quality issues if measurement equipment drifts by only 0.005 mm.

To minimize inspection uncertainty, many manufacturers rely on industrial-grade digital calipers and micrometers with certified calibration traceability.

Industrial Digital Calipers:

https://www.hoshingprecision.com/product/vernier-caliper-2/

Industrial Digital Micrometers:

https://www.hoshingprecision.com/product/digital-micrometer/

Regular calibration according to ISO-compliant inspection procedures helps ensure measurement consistency and reduces the likelihood of non-conforming products entering the supply chain.

Shipping Damage and Packaging Standards

Precision measuring instruments require careful packaging during international transportation.

Common risks include:

Impact damage

Moisture exposure

Corrosion during sea freight

Calibration drift caused by improper handling

Protective foam inserts, reinforced cartons, and moisture-resistant packaging have become standard requirements for export-oriented measuring tool manufacturers.

Companies such as Hoshing place significant emphasis on packaging integrity and export inspection procedures to support reliable international shipments.

Sourcing Stability and Supplier Qualification

A measuring tool supplier should be evaluated based on long-term supply capability rather than individual order pricing.

Key supplier evaluation factors include:

Manufacturing consistency

Quality management systems

Export experience

Inventory availability

Lead time stability

Calibration support

For industrial distributors managing hundreds of SKUs, sourcing stability often becomes more important than obtaining the lowest purchase price.

Unexpected supplier disruptions can create significant downstream costs across the entire supply chain.

Warehouse Handling and Inventory Management

Even high-quality measuring tools can lose performance if stored improperly.

Recommended warehouse practices include:

Controlled temperature environments

Humidity monitoring

Protective storage cases

Scheduled calibration verification

FIFO inventory management

Industrial metrology equipment should be treated as precision assets rather than standard warehouse inventory.

Proper storage helps maintain measurement repeatability and extends product service life.

Procurement Cost vs Total Cost of Ownership

Many procurement teams evaluate measuring tools based on initial purchase cost.

However, a more effective approach is to consider Total Cost of Ownership (TCO).

Factors influencing TCO include: Factor Impact on Cost Calibration frequency Maintenance expenses Product lifespan Replacement costs Measurement repeatability Scrap reduction Packaging quality Damage prevention Supply stability Inventory planning Quality consistency Production efficiency

In many cases, a higher-quality measuring tool generates lower long-term operational costs than a lower-priced alternative.

Real-World Manufacturing Example

A European automotive supplier producing transmission components experienced recurring dimensional deviations during incoming inspection.

Root cause analysis revealed inconsistent measurement results caused by variation in handheld inspection tools supplied by multiple vendors.

After standardizing inspection equipment and implementing calibration traceability requirements, the company achieved:

28% reduction in inspection-related defects

Improved process capability

Lower rework costs

More stable supplier quality performance

This case demonstrates how measurement systems influence not only production quality but also overall supply chain efficiency.

Frequently Asked Questions

Why are digital micrometers preferred for tight tolerances?

Digital micrometers typically offer higher repeatability and resolution than calipers, making them suitable for precision applications requiring tighter dimensional control.

How often should measuring tools be calibrated?

Calibration frequency depends on usage intensity and quality requirements. Many industrial facilities perform annual calibration, while high-precision operations may require more frequent verification.

What is the biggest supply chain risk when sourcing measuring tools?

Inconsistent product quality and unstable lead times are often greater risks than unit price differences.

How does packaging affect measuring tool reliability?

Proper packaging protects measuring instruments from physical damage, moisture, and environmental exposure during transportation and storage.

Conclusion

Selecting measuring tools for tight tolerance applications involves much more than comparing specifications. Defect rates, sourcing stability, packaging standards, inventory management, and long-term procurement costs all influence the effectiveness of a measurement system.

For manufacturers, distributors, and industrial buyers, investing in reliable metrology equipment is not simply a quality decision—it is a supply chain strategy that supports production stability, customer satisfaction, and long-term operational efficiency.
