In the sheet metal working industry, the efficiency of production processes and the quality of the end result also depend on components that are often considered secondary. Among these, plastic components play a key role in the protection, safety and handling of the various processing steps.
BMP TAPPI develops plastic components for sheet metal working, designed to guarantee protection, reliability and operational continuity in industrial processes. Solutions for pipes and flanges are integrated into production cycles to preserve processing quality and support consistent performance throughout the line.
The role of plastic components in sheet metal working
Sheet metal working components do not have a structural, but an operational and preventive function. More specifically, those made of plastic are used to:
- protect surfaces, joints and connectors
- preserve component quality during machining operations
- prevent the ingress of dust, debris and contaminants
- facilitate transport, storage and assembling
Thanks to its versatility, plastics make it possible to obtain light, resistant solutions that can be adapted to different geometries, which are typical of sheet metal work.
Protection of pipes and flanges: a critical need
In sheet metal work for pipes and flanges, protecting the joints is an essential step.
Plastic plugs, caps and flange covers make it possible to
- protect the edges and surfaces from impact and abrasion
- prevent deformation during handling
- preserve the cleanliness inside the tubes
- maintain dimensional tolerances before assembling
These products are particularly useful during intermediate stages of the production cycle, where the risk of damage is highest.
Operational functions of plastic components in sheet metal working processes
Within sheet metal working processes, plastic components perform several operational functions, including:
Mechanical protection
Caps and plugs protect threads, holes and machined surfaces from accidental impacts and mechanical stress.
Isolation and separation
Plastic components allow sensitive parts to be isolated during surface treatment or finishing operations.
Handling support
Protections reduce the risk of damage during internal and external transport of semi-finished products.
BMP TAPPI’s plastic components for sheet metal working: uses
In sheet metal working, plastic components do not perform a single function, but meet different operational needs throughout the various stages of the production process.
For this reason, the solutions developed by BMP TAPPI can be divided according to the function performed within the industrial cycle:
- handling and transport
- protection of surfaces, holes and threads
- masking and protection during machining and processing
Handling and transport
In sheet metal working, internal and external handling is one of the most critical phases in terms of risk of damage.
BMP TAPPI proposes:
- Tube caps and protectors, ideal for preserving joints during handling, storage and transport – check the BMP TAPPI’s tube caps and protectors category
- Specific flange caps and protectors, used to protect pipe joint surfaces during transportation and logistics – check out the selection on BMP TAPPI Flange Protection
- Tube caps and end caps that facilitate gripping and minimise the risk of accidental impacts.
Surface, hole and thread protection
Protection is one of the main functions of plastic components in sheet metal working, especially for pipes and flanges intended for further processing.
The most commonly used BMP products include:
- Inserts and plugs for closing holes on sheet metal, designed to protect holes from contamination and deformation, maintaining the quality of machining operations and facilitating assembling stages – discover the BMP TAPPI’s products Caps for closing holes on sheet metal
- Plastic caps and undercaps, which can be applied to threads, holes and small profiles to prevent dust, swarf or contaminants from entering – check out the offer in the category BMP TAPPI’s plastic caps and undercaps
- Thread protectors and thread caps, designed to protect male and female threads during machining, transportation and storage – discover the BMP TAPPI range of thread protectors and thread caps
- Plastic solutions with specific geometries to protect sensitive surfaces prior to final assembling.
Masking and protection during machining and processing
During processes such as welding, surface processing or machining, some areas need to be temporarily isolated.
In these cases, the following are used:
- Oil and chemical resistant caps and plugs, designed to withstand specific operating conditions
- Silicone caps, suitable for high temperature applications and repeated processing cycles – discover BMP TAPPI’s range of silicone caps
- Paint caps, used for masking holes, threads and surfaces during painting and finishing processes – check out BMP TAPPI’s Paint Caps category
- PVC caps and ferrules, which are flexible and easily applied solutions for temporary protection of edges, contours and sensitive surfaces – check out the PVC caps and ferrules products
- Easily applicable and removable plastic components, ideal for protecting sensitive parts of semi-finished products
Targeted insulation makes it possible to protect sensitive parts without interfering with the production process.
Uses of plastic components in major industrial sectors
Plastic components for sheet metal working are applied across the board in various industrial sectors, where they provide protection and operational support along the various stages of the production process.
They are particularly essential in areas such as:
- Sheet metal working, where they protect the edges, holes and machined surfaces during cutting, bending and finishing.
- Welding, to isolate and protect sensitive parts from splashes, heat and contamination.
- Tube and flange manufacturing, where protecting the ends is essential to preserve geometries, internal surfaces and tolerances.
- Metalwork, where plastic components help reduce damage during handling, assembling and storage.
