Klarm Mould

Selecting an injection molding company can become an overwhelming process, especially when you consider that you are choosing a partner who can work with you to help you bring your products to life. Injection molding is a process of manufacturing rubber or plastic material to a specific shape by injecting the material into a specially crafted mold. The process is commonly used in the manufacture of various plastic products, including automotive dashboards, wire spools, bottle caps, electronic casings, and instrument housings. Here are a few pointers to help you choose the right injection molding company:

* Choose an experienced company – Find a company that has at least five years of experience in serving the type of business you run. That way, you can be confident in their ability to understand your unique injection molding requirements and the kinds of products you are producing.

* Find out who they serve – A seasoned injection molding company is flexible in dealing with a wide range of industries, most especially businesses involved in the automotive industry and in the manufacture of medical equipment, mobile phones accessories and cases, home appliances and kitchenware, glass and office accessories, printers, cameras, and 3D frames.

* Go over their services – Reputable injection molding companies can make custom molds from the scratch to be used for your project, especially if your product has a unique shape and one-of-a-kind features. Apart from injection molding, they can provide services like rotational, metal die casting, silicon, extrusion, and blow injection molding. They are able to handle high volume production, too.

* Find out where they are based – Some of the best injection molding companies are in China. They offer reasonably priced services and high-quality results that can rival that of locally based injection molding specialists. Despite their location, they are known around the world and are continuously expanding their reach by providing professional sales and engineering teams at your service. That way, you can easily tell them what you need, and your products can be finished in no time.

* Look for reviews – You can never be too sure of the reputation and reliability of an injection molding company overseas until you have heard or read what other customers are saying about them. Hence, be sure to look up reviews and testimonials on the company.

The Part That Precision Press Molding Plays in Creating Car Parts

The Part That Precision Press Molding Plays in Creating Car Parts

It is highly likely that many of you will have never really taken the time to consider just where the parts that make up a car come from. You will take a trip down to an auto body shop and pick out your needed parts without ever thinking about how those parts came into being.

Well, a good portion of car parts are created using a specially designed press mold which has been built and supplied to the manufacturer from companies.

These press molds have to undergo a number of different tests to ensure that they are exact in size and shape and are what the automotive manufacturer is looking for.

Once these press molds have been skillfully designed, developed, and constructed, they are sold to the automotive manufacturer who then uses these molds to mass produce the car parts that the molds represent.

What Parts are generally made By Press Molds?

Press molds can be developed and constructed for a wide variety of different car parts. Everything from the exterior paneling, interior paneling, and seat covers, and even the heads of the gear sticks are constructed using a high quality press mold. In fact there is not too much that cannot be created as even parts of the chassis are often created by press molds.

A number of different materials can be used in a press mold and they are usually created using a combination of a hydraulic press, some heat, and a raw material that could be anything from metal alloy, rubber, or plastic.

The process of creating the parts includes placing the materials in the press mold, applying heat and pressure from the hydraulic press before the finished product is ready to be finalized through being painted and flashing.

The Benefit of Using Compression Molding

The main benefit of having press molds built and used for the manufacture of car parts is that it is an extremely cost effective process. Molds do not cost that much, especially from well renowned brands whilst labor costs are also not as much as what would be found with other methods.

Additionally, there are only small amounts of wasted materials as any they can be simply be recycled and used again in a future mold. The savings made by here can be better spent by car manufacturers on other areas of the product that could essentially make them better.
The final benefit that is by using a press mold for car parts, you can be sure of a consistency across all parts made as well as being produced at an efficient rate.

•Material Supplier / Toolmaker: Asahi Kasei Plastics North America / Liberty Molds, Inc., J&J Tool & Mold Ltd.
•Material / Process: Leona® 90G60 B3374 PA 6/6 / 6I / injection molding
•Description: In order to support greater design freedom for any shape and length register vanes while meeting stiffness, durability, and perceived quality requirements, a partially aromatic injection-molded PA 6/6 / 6I resin was used to boost modulus without increasing wall thickness or adding glass reinforcement to achieve a high-quality, MIC Class A surface without paint. Owing to the "kinked" crystalline structure of the semi-aromatic PA resin, crystallization rate can be better controlled, so parts fully pack out before skins freeze off, leading to a resin-rich surface with a smoother surface and better appearance, eliminating the need to paint.

Extremely rigid construction
high-quality automotive molding
Image by felixdaacat
Superior passive safety is only one benefit of the extreme rigidity of a full carbon fiber monocoque – very high torsional rigidity is another. The monocoque is connected at the front and rear with equally rigid aluminum sub-frames, on which the suspension, engine and transmission are mounted.

The entire body-in-white of the future V12 model weighs only 229.5 kilograms (505 lbs) and boasts phenomenal torsional rigidity of 35,000 Newton meters per degree of twist. This guarantees a superb feeling of solidity, but, more importantly, extremely exact wheel control with excellent steering precision and sensitive feedback. For the dedicated driver, both are essential for truly enticing driving pleasure. The new Lamborghini flagship responds to the most minute steering input with the stunning precision of a perfectly balanced race car.

Depending on the form, function and requirements of the individual elements, the Lamborghini development team selected from three main CFRP manufacturing methods within its technology tool kit. They differ not only in their production processes, but also in the type of carbon fiber and its weave and, most importantly, in the chemical composition of the synthetic resin used.

Resin Transfer Moulding (RTM): In this process the carbon fiber mats are preformed and impregnated with an exact amount of resin. Afterwards, they are cured under heat while the part is in the mould. Lamborghini has achieved a major breakthrough by further developing this method. Using the patented “RTM-Lambo” process, the final mould is no longer a heavy, complex metal piece, but is made instead from lightweight carbon-fiber parts, thus making the manufacturing process faster, more flexible and more efficient.
An additional benefit of the RTM-Lambo process is the low injection pressure that doesn’t require expensive equipment.

Prepreg – The carbon fiber mats used in this method, commonly known as prepreg, are pre-injected by the supplier with a thermosetting liquid resin and must be stored at a low temperature. The mats are then laminated in molds and cured under heat and pressure in an autoclave. Prepreg components are complex to make, but have an extremely high-quality surface finish (Class-A surface quality) and are therefore the preferred option for use in visible locations.

Braiding – These components are manufactured by using RTM technology. This carbon fiber weave technology is derived from the textile industry and used to make tubular components for special applications such as structural roof pillars and rocker panels. The woven components are made by diagonally interweaving the fiber in several layers.

The monocoque of the new V12 super sports car is constructed using these technologies applied in a series of special processes. One significant advancement Lamborghini realized is the ability to use already-assembled monocoque elements as the mould for the next step in the process. This makes for a considerable simplification of the manufacturing process compared with conventional methods.

Epoxy foam components are also used within the monocoque. They are placed in strategic points to increase the stiffness of the monocoque by working as spacers between the composite layers while also dampening noise and vibration. In addition, aluminum inserts are laminated into the front and rear surfaces to facilitate connection with the aluminum front and rear sub-frame elements.

Because of the complexity of the materials and process outlined above, Lamborghini decided to produce its new monocoque completely in-house, managing one strategic step in the production process.

Quality control is an absolutely crucial factor – every single monocoque is measured to exacting tolerances of only 0.1 millimeters, facilitating the extreme precision of the overall vehicle. Quality control starts with the purchase of the carbon fiber parts. Every delivery of carbon fiber is certified and the material is checked regularly for compliance with quality standards. Lamborghini worked together with its suppliers to develop a world-exclusive fiber and resin system for its RTM technology. Ultimately, these materials and processes constitute an important part of Lamborghini’s worldwide leading expertise in the field.

Carbon composite materials – A key technology for tomorrow’s high-performance automotive engineering

These materials made from CFRP combine the lowest possible weight with excellent material characteristics – they are very light, extremely rigid and exceptionally precise.

Furthermore, CFRP materials can also be formed into highly complex components with integrated functions. This reduces the number of individual parts when compared to traditional metal construction – thus enabling further weight reduction. Lighter cars have lower fuel consumption and fewer CO2 emissions. Most significantly, however, it improves the power-to-weight ratio – the deciding factor in the overall feel and performance of a sports car. A super sports car built using CFRP accelerates faster, has superior handling and better braking.
