G

Language Register: Technical English in Manufacturing

Rule

In technical English for manufacturing, the passive voice is frequently used to describe processes and procedures. The structure is: Object + is/are + Past Participle. This sounds more professional and objective than the active form.

Examples

"The furnace is heated to 1,200 degrees Celsius."

Correct: Passive for process descriptions. The furnace is heated to 1,200°C.

"The quality inspection is carried out before shipment."

Correct: 'is carried out' is a standard phrase for conducting inspections.

"We are manufacture the components in-house."

Wrong! Correct: 'We manufacture the components in-house.' (Active) or 'The components are manufactured in-house.' (Passive).

"All products are tested according to DIN standards."

Correct: 'according to' = in accordance with. Typical phrasing for quality standards.

Tips

  • •Use passive voice for process descriptions: 'The steel is welded...'
  • •Use active voice for your team's direct actions: 'Our engineers design...'
  • •Always include units with technical terms: '1,200°C', 'tolerance of ±0.5mm'
  • •In English: decimal point not comma (1.5 not 1,5) and comma as thousand separator (1,200 not 1.200)

Tip

Practical Tip: Watch the number format! In German, you write 1.200,50 € -- in English, this becomes 1,200.50 €. The decimal point and comma are swapped! This small difference can lead to costly misunderstandings in technical documents and quotations.

Exercise 1: Complete the Technical Phrases

1/50

The furnace is ______ to operating temperature within two hours.

Past participle of 'heat'

Exercise 2: True or False?

1/50

In technical English, you should avoid the passive voice because it sounds unprofessional.

The Challenge: Technical Staff and English

Why Manufacturing Companies Need Specialized English Training

The challenges Niermann Ofenbau faced are typical for mid-sized manufacturing companies in Germany. The employees are excellent specialists -- engineers, technicians, sales representatives -- but their English skills often date back to their school days.

The most common problems at a glance:

  • Technical correspondence: Emails to international clients often sound too direct or informal because German language patterns are transferred one-to-one
  • Client meetings: During factory tours, the technical vocabulary needed to explain production processes clearly is often missing
  • Trade fair appearances: At international fairs like the Hannover Messe, employees must present and negotiate in English spontaneously
  • Technical documentation: Operating manuals and data sheets must be written in correct technical English

The key to success lies in training that is tailored precisely to industry-specific needs. General Business English is not enough for a company like Niermann Ofenbau.

Practical Examples from Daily Business

Workplace Communication: Emails, Factory Tours, and Trade Fairs

One of the biggest improvements at Niermann Ofenbau was in written communication. Many employees translated German phrases directly into English -- sometimes with unintended results.

For example: The German sentence "Hiermit sende ich Ihnen die Spezifikation" became "Herewith I send you the specification" -- correct, but extremely formal and outdated. Better: "Please find attached the specification" or even more naturally: "I'm sending you the specification as discussed."

The training proved especially valuable during factory tours. Employees learned to explain production processes in English:

  • "Let me show you our production floor. This is where we assemble the furnace components."
  • "As you can see, all welding is done by certified professionals."
  • "Would you like to see our testing facility? We run quality checks on every unit."

These phrases sound natural, professional, and welcoming -- exactly the right tone for a client visit.

Tips for Successful Corporate Training

How to Implement Successful English Training in Your Company

Niermann Ofenbau's experience shows: tailored training is the key to success. Here are the most important insights that also apply to your company:

1. Conduct a needs analysis: Which employees need what kind of English? A sales representative has different needs than a production engineer. At Niermann, three groups were formed: Sales/Management, Engineering/Production, and Reception/Administration.

2. Industry-specific content: Training should use real scenarios from daily work. Emails to actual clients, presentations about your own products, and role-plays for client meetings are much more effective than generic textbook exercises.

3. Regularity over intensity: Niermann Ofenbau opted for weekly 90-minute sessions instead of infrequent full-day trainings. This kept the learning rhythm consistent and employees could immediately apply what they learned in their daily work.

4. Practice-oriented success measurement: Instead of standardized tests, success was measured against real situations: Can the employee independently write a client email? Can they conduct a factory tour in English?

Final Quiz: Technical English for Manufacturing

Question 1 / 7

What is the correct translation of 'Inbetriebnahme' (putting into operation)?
