Here are some more information for Side Mouldings:

Threaded inserts are fastener-related devices constructed of metal or plastic materials. They are generally used to provide thread tracks for screws or bolts. These inserts can allow a fastener to form a more secure attachment to soft or pliable surfaces that would otherwise reject fastening, repair a damaged thread track, or install threads into a workpiece without relying on a more elaborate production process. Threaded inserts are usually placed inside an existing hole or slot, and they feature an external design that allows them to be lodged securely, along with a cylindrical inner cavity lined with threads.

Fastener inserts can be made from a wide range of materials, including metals such as brass and steel, and plastics such as PVC. Likewise, they are available in a variety of design types depending on their application. Molded inserts are used in plastic fabrication cavities, while key-lock inserts are employed for repairing stripped thread holes. Threaded brass inserts are most often used for fastening plastic materials, although they can also be applied to wood and other surfaces as well. Installing these inserts is usually a multistage process, and can sometimes require special equipment or techniques to accomplish.

Threaded Inserts in Wood

Installing a threaded brass insert into a wood surface requires a certain degree of care. A threaded rod with a length depending on the specific application needs will be required, along with a few similarly-sized nuts, masking tape, and copper tubing with an internal diameter slightly larger than the external diameter of the threaded rod.

First, a pilot hole must be drilled into the wood at the point where the threaded insert will be installed. To help keep the angle of insertion perpendicular to the surface, it can be helpful to mount the workpiece in a drill press, but it is important that the drill press is off during the procedure. The workpiece should not be clamped too tightly because the threaded rod should be able to rotate inside the copper sleeve. The rod can then be twisted into its slot with a wrench, while masking tape is used to keep it from slipping out of the copper tubing, which functions as a sleeve. Depending on the hardness of the wood, considerations may need to be taken for clearing chips from the area.

Threaded Inserts in Thermoplastic

Putting threaded brass inserts in a thermoplastic material, such as acrylic, involves a different set of equipment and methods than those used for wood surfaces. In some cases, the insert may need to be melted into the workpiece in order to form a secure joint. Generally, this occurs on the more rounded side of an acrylic piece as a smaller amount of melted plastic will gather near the insert and the installation will be easier. The standards steps in such a procedure include:

o Positioning: A threaded brass insert usually has a taper on one side to help with insertion into a slot. Inserts should be placed along the surface of the thermoplastic workpiece in their intended spots, ideally along a series of predrilled holes.

o Insertion: The workpiece should be clamped or moved to ensure that the insert holes are overhanging the edge of a bench or other work surface, and a heated soldering iron may then be pressed into the threaded insert. Applying a slight amount of pressure onto the soldering iron will help push the insert straight down into the material.

o Protrusion: The soldering iron can be used to guide the insert and keep it straight as it enters the workpiece. The insert should be pushed until it lies flush with the top surface of the workpiece, although there may be a small accumulation of melted plastic that rises over the insert. Depending on the application requirements, the insert should also be checked to see if it lies flush with the bottom half of the plastic surface.

o Inspection: After the threaded insert has been installed, it may be helpful to use a screw or bolt to verify its positioning. If the screw attaches at a bent angle, the soldering iron can be applied to reposition it correctly.

It may be necessary to preheat an insert on the soldering iron before beginning installation, especially if working with a large brass insert. Alternatively, a drill press can be employed to grip the workpiece while heat is applied to the insert, although the press should not be turned on during the process.

Grp Mouldings

GRP Mouldings are products manufactured from a modern day composite material, GRP stands for Glass Reinforced Plastic, GRP is also known as FRP, which stands for Fibre Reinforced Plastic, but the most widely used term for this truly unique material is Fibreglass.

GRP Mouldings are designed and manufactured for use in most industry sectors, these industry sectors range from, construction, leisure, marine, aerospace, automotive, defence, and much more.

Designers, architects, and end-users alike have found that glass reinforced plastic has few constraints or limitations when it comes to design and is only limited by your imagination, GRP Mouldings can be manufactured to any size, shape, or colour required, these moulded components display a superior moulded finish that can be made to replicate bronze, stone, wood, granite or any BS or RAL colour required, these great moulded finish's can also be UV stabilised and can withstand environmental extremes when used for outdoor applications, also one of the great things that make GRP the composite of choice, is that it can be specifically tailored to meet the end users requirements, be it fire-retardantcy, chemical-resistance, corrosion resistant, or product that can be engineered to cope with specific loads and stresses, basically the applications for GRP Mouldings are varied, with new ideas taking shape daily.

GRP Mouldings are manufactured with the aid of a mould, the mould is a reverse of the product, the mould can be male or female depending upon the design, moulds are normally made from fibreglass, but can also be made from timber, latex rubber, or aluminium, once the mould has been waxed and prepared with the relevant release agents, the gel-coat can be painted or sprayed onto the mould face, once the gel-coat has cured, the glass fibre is laid into the mould against the gel-coated surface, the glass fibre is then impregnated with resin, the saturated glass fibre is then rolled with a special roller to remove the any trapped air and to consolidate the glass fibres, more glass fibre is then applied and saturated with resin until the desired thickness is achieved, the laminate is then allowed to harden and cure, once the laminate has cured the GRP Moulding can be released from the mould.

As discussed at the beginning of this article, GRP mouldings are manufactured for a wide variety of end user applications, some of which are,

Architectural components, Boat hulls and associated components, Water slides and Theme park rides, Motorcycle fairings, Lorry wind deflectors and body kits, Shower trays and Baths, Aircraft cowlings and components, Race car body work, Modular buildings, Walkways and Bridge cladding, Mobile phone mast enclosures, Airport furniture, Signage and Display, Train bodies and interior components,

And so on.

So whether you are a designer, architect, or end-user, and you are looking at your next project, the answer is simple, GRP, this truly innovative composite material has real potential.......

chipped paint on side door moldings at dealership getting oil change? do i have a chance to get compensatio?

i can almost swear those paint chips weren't there before. about 5 of them. they look "fresh" bc the paint is scrunched up and lose. (if it was old i think it would have fallen off by now). i talked with the service manager and 'till the death he is denying that they did anything and that it was probably someone opening their doors on my car. is there anything else i can do? Talking with him got me absolutely nowhere. what should i do? i am furious!!
If I can't prove it is it pointless to argue?

If you can prove it. Any cameras ?
