How to write successful specifications?

In industry, specifications are a key document that define the expectations, constraints and specifications of a project. Properly conceived, it serves as a guide for all parties involved, and ensures that the end result matches the initial requirements.

At AMP-POLYMIX GROUPwe support our customers right from this crucial stage, advising them on the plastic best suited to their specific needs, applications and requirements.

Here are the essential elements for drawing up an effective specification and guaranteeing the success of your project.

1. Project presentation: defining objectives

Start with a clear introduction that details :

• The main objective: what problem does the project need to solve? What functionality or innovation do you want to deliver?
• The final application: is it a medical product, an automotive part, cosmetics packaging, sports equipment, etc.?
• Target audience: is it for professional or consumer use?

Here’s a concrete example: if you’re developing a part for a lightweight bicycle, mention whether it’s intended for competition or leisure use.

2. Technical constraints

To choose the most suitable material, it is essential to precisely define the technical constraints related to the application and its manufacture:

• Production: which processing machines and processes will be used?
• Operating environment:
  • Temperature (exposure to heat, cold).
  • Moisture and UV resistance.
  • Chemical compatibility (contact with aggressive products, solvents or food).
• Mechanical properties required:
  • Impact, abrasion and tensile strength.
  • Flexibility or rigidity depending on the application.
• Desired lifespan: disposable or designed for extended use?

3. Regulatory requirements and certifications

Each sector imposes strict standards to which materials must conform:

• Food contact: compliance with FDA and CE 10/2011 regulations for materials intended for food packaging.
• Sector medical ISO 10993 standard for biocompatibility.
• Automotive sector: resistance to mechanical and thermal stress according to industry standards.
• Eco-responsibility : use of recyclable and/or bio-sourced materials to meet ecological expectations.

It’s essential to specify these constraints from the outset, to avoid any problems downstream.

4. Aesthetics and design

Design plays a major role, especially for products intended to be visible to the end consumer. Mention :

• Desired finishes (matte, glossy, textured).
• Colors and customization options.
• Manufacturing process limitations (injection molding, extrusion, 3D printing, etc.)

5. Budget and volumes

Realistic specifications must include :

• Allocated budget: enables us to target appropriate solutions, whether for high-performance polymers or commodities.
• Planned production volumes: large quantities may justify investment in technical materials or customized molds.

6. Deadlines and planning

Indicate project milestones and expected deadlines:

• Delivery of prototypes.
• Production lead times.
• Testing and validation.

A clear schedule facilitates coordination between internal teams and suppliers, while avoiding delays.

A well-structured specification is the cornerstone of a successful project. By detailing objectives, constraints and specific expectations, you put all the chances on your side to obtain a product that meets your requirements.
