Sure, I can help you improve this code. Here's a possible rewrite:

```typescript
import { TranslateService } from '@ngx-translate/core';

// ...

getSectionTitle(item: SectionViewModel): string {
  switch (item.sectionTypeName) {
    case SPECIFICATION_SECTION_TYPES.SUPPLY_CONTROL_PLAN:
      // Use the specific internationalized messages
      return `${this.translateService.instant('S001_CONTROL_PLAN.NODE.SUPPLY_CONTROL_PLAN')} - ${this.translateService.instant('S001_CONTROL_PLAN.NODE.APPENDIX')}`;
    case SPECIFICATION_SECTION_TYPES.S001_CONTROL_PLAN_DESIGN:
      return `${this.translateService.instant('S001_CONTROL_PLAN.NODE.CONTROL_PLAN')} - ${this.translateService.instant('S001_CONTROL_PLAN.NODE.DESIGN')}`;
    case SPECIFICATION_SECTION_TYPES.S001_CONTROL_PLAN_PRODUCTION:
      // Use the specific internationalized messages
      return `${this.translateService.instant('S001_CONTROL_PLAN.NODE.CONTROL_PLAN')} - ${this.translateService.instant('S001_CONTROL_PLAN.NODE.PRODUCTION')}`;
    case SPECIFICATION_SECTION_TYPES.APPENDIX:
      return this.translateService.instant('DOCUMENT.APPENDIX');
    default:
      // Use a generic format for default sections
      const title = item.tocIndex
        ? `${item.tocIndex + 1}. ${item.heading}`
        : item.heading;
      return title;
  }
}
```

Explanation:

- I've imported the `TranslateService` interface from `@ngx-translate/core` to have access to the `instant` method.
- For specific internationalized messages, I've used your original format within the `switch` case block.
- For default sections, I've used a generic format that includes the index in the table of contents (if any) and the section heading, separated by a dot. This ensures that the format remains consistent for all sections, even if they don't have a specific internationalized message.

If you're using a newer version of Angular than 12, you can use the `ngx-translate/shared/translate.service` module and inject it directly in your component/service.

To improve the code, I would suggest using a data-driven approach, which makes the code more maintainable and extensible. You can create a mapping object to store the translation keys for each section type. This way, you can easily add or remove section types without modifying the switch statement.

Here's the improved code:

```typescript
interface SectionTranslationMap {
  [key: string]: {
    prefix: string;
    suffix: string;
  };
}

const sectionTranslationMap: SectionTranslationMap = {
  [SPECIFICATION_SECTION_TYPES.SUPPLY_CONTROL_PLAN]: {
    prefix: 'SUPPLY_CONTROL_PLAN.NODE.APPENDIX',
    suffix: 'SUPPLY_CONTROL_PLAN.NODE.SUPPLY_CONTROL_PLAN',
  },
  [SPECIFICATION_SECTION_TYPES.S001_CONTROL_PLAN_DESIGN]: {
    prefix: 'S001_CONTROL_PLAN.NODE.CONTROL_PLAN',
    suffix: 'S001_CONTROL_PLAN.NODE.DESIGN',
  },
  [SPECIFICATION_SECTION_TYPES.S001_CONTROL_PLAN_PRODUCTION]: {
    prefix: 'S001_CONTROL_PLAN.NODE.CONTROL_PLAN',
    suffix: 'S001_CONTROL_PLAN.NODE.PRODUCTION',
  },
  [SPECIFICATION_SECTION_TYPES.APPENDIX]: {
    prefix: '',
    suffix: 'DOCUMENT.APPENDIX',
  },
};

getSectionTitle(item: SectionViewModel): string {
  const sectionTypeName = item.sectionTypeName;
  const mapEntry = sectionTranslationMap[sectionTypeName];

  if (mapEntry) {
    return `${this.translateService.instant(mapEntry.prefix)} - ${this.translateService.instant(mapEntry.suffix)}`;
  }

  const title = item.tocIndex ? `${item.tocIndex} - ${item.heading}` : item.heading;
  return title;
}
```

This refactored code creates a mapping object (sectionTranslationMap) that holds the translation keys for each section type. The getSectionTitle function now checks whether the sectionTypeName exists in the mapping object, and constructs the title accordingly. If the sectionTypeName is not found in the mapping object, it falls back to the original default behavior. This makes it easier to add, remove, or modify section types without touching the function itself.
