Why is mould important for manufacturing automotive lamps?

Figure 2: Automotive Lamp Mould

The lights in modern-day cars are doing more than just lighting dark roads. Many OEMs and automobiles are using it as their design signature. An automotive company (Audi) was the pioneer of the trend in 2004, the company introduces daytime running lights in the international market. Since then, beaming technology has advanced rapidly, making auto lamp manufacturing an integral part of the automotive industry. These lamps are used in the front, sides, and back of the vehicle, active lighting throws light around edges, and even laser high beams are emerging.

Importance of auto lamp molds

It is imperative to have a mould for the making of the lamps. Multiple pieces of lamps can be made from a single mould. Front and rear light lamps go through quick design cycles because manufacturers are making style changes every year. Production of these lamps of injection-moulded plastic components requires complex mould tools, and their long lead times can readily constrain or delay model facelifts. Indeed, designers and manufacturers are under immense pressure to accelerate auto lamp mould production, and go4mould is equipped to accommodate them accordingly.

What are the machining technologies used to manufacture auto lamp moulds?

Go4mould utilizes top-notch machinery for the designing and production of all sorts.
Two types of technology are used for manufacturing Moulds;


Go4mould is decked with all kinds of precision milling machines, grinding machines, CNC machines, EDM machines, wire cutting machines, and more, enabling us to manufacture and repair different Moulds rapidly.

What are the machining operations performed in manufacturing auto moulds?

Machining operations

There are two primary operations for manufacturing lamp Moulds.
1.CNC Machining
2.EDM Machining

CNC machining: This is a machining process in which a workpiece is shaped into a designed geometrical shape and size by using a controlled material removal process. This process depends mainly upon the use of machine tools in addition to the power and hand tools.
The Two Sub-Processes in Manufacturing Lamp Moulds
· Milling
· Turning

Milling is a subtractive machining process that uses various machine toolsets to efficiently precision-cut aluminum or steel into a defined geometrical mould shape. Milling machines rapidly produce end-use parts with the adoption of 3- or 5-axis processes.
CAD/CAM programming software enables the machine to shape the chunk of metal into the designed lamp mould.

Turning is a subtractive machining process that uses a cutting tool, typically a lathe, to achieve the designed shape of the mould.
There are four specific turning operations used to manufacture moulds:

  • Turning is one of the most fundamental machining processes, which involves a rotating part being cut by a cutting tool moving along the axis of rotation of the workpiece. Turning can be performed on both the external and internal surfaces of the Mould.
  • Facing is the most important process, performed in the production of lamp Moulds. It moves the cutting tool perpendicular to the workpiece to cut it into the desired shape.
  • Parting creates deep grooves that remove an entire or partial segment from the workpiece.
  • Grooving is the cutting of grooves at a required depth and can be performed on internal and external sides of the mould. It encompasses face grooving, drilling, knurling, polygonal turning, and threading.

Spark machining – EDM

Figure 3: Electric Discharge Machining

In this process, the material is removed from the workpiece with the help of an electric spark. This process can be performed in two ways:

  1. EDM wire cut
  2. Sinker EDM

Rapid reiterations of electrical current discharges between two electrodes, the tool-electrode, and the workpiece-electrode, work to remove material from the mould piece without ever making physical contact.

Processes included in manufacturing auto lamp mould?

Go4mould makes a design first to carry out machining operations for manufacturing auto lamp molds.

We at go4mould have a four-step designing process.

  1. DFM Analysis
  2. 2D Drafting
  3. 3D Design
  4. Machining Operations.

DFM Analysis

Designing of DFM analysis or manufacturing analysis precedes mould designs.

Feasibility research is carried out, carefully evaluating:

  • Moulding axis/pivot.
  • Parting-line, evaluating signs of the finished product.
  • Any pieces of the part to be obtained from movable parts/inserts in the mould.
  • Thicknesses, avoiding the fine-tuning problems.
  • Ejection
  • Form
  • Injection point or mould Flow

Go4mould will send this feasibility analysis to the client in the document form named ‘Concept.’

2D drafting

Software Used: CADKEY

The second step in the process of manufacturing this mould is making a 2D draft. We at go4mould pay attention to detail for a preliminary evaluation of the mould in a concise amount of time.

Then the problems are highlighted along with the information of material delivery time.

3D design

Design crafted with the smallest of details acknowledging all mechanical, functional, and economic aspects.

Go4mould is fully equipped with cutting-edge modern-day technology to provide you with the best service in designing, testing, and manufacturing high-quality products.

It is defined in the above part of the go4mould ultimate FAQ guide.


Materials used in manufacturing auto lamp moulds?

Material Selection for injection mould
Material Selection for injection mould

Figure 4: Material Selection for Auto Lamp Mold

The prerequisite for quality mould manufacturing is the choice of top-tier materials. When choosing mould materials, mould designers examine various factors, including machining ease, weldability, abrasion resistance, hardness, corrosion resistance, and durability.

Aluminum: It is a long and popular choice for prototype moulds, is gaining acceptance among moderate-run production moulds. Improved aluminum alloys, such as QC-7, have greater concentration and hardness than standard aircraft-grade aluminum.

Steel:  It is a standard choice for most high production moulds designed for engineering plastics is built from high-quality tool steel. Cavity and core steels vary based on the production requirements, machining complexity, mould size, mechanical needs, and the abrasive or corrosive nature of the moulding resin.

Other commonly used mould steels are:

  • 45 #
  • 40Cr
  • P20
  • 2738
  • 2316
  • 718
  • NAK80
  • H13
  • S136

According to the customer’s mould use and life requirements, go4mould recommends the best choice for mould steel.

What are the available surface treatment processes for auto Moulds?

Surface Treatments

To varying degrees, finished goods represent the finish and texture of the moulding surface. Fine scratches and roughness on the moulding will create a non-glassy part surface and potential part ejecting problems. Thus, making surface treatment is a vital operation of the job.



There are three processes available at go4mould for surface treating the mould:

  1. Polishing
  2. Photo Etching
  3. Coating

Polishing: High gloss finishes typically require a sequence of polishing steps using progressively finer silicon carbide stones arranging from 220 – 900 grit. The surface is polished and buffed to a more refined detail with increasingly finer diamond pastes.

Greater the steel hardness, the higher the gloss.

A surface hardness of at least Thirty (30) HRC is usually required for moderately fine gloss finishes. High gloss finishes typically require hardness above 50 HRC.

Photo Etching: This method uses an acid etching process to attain various surfaces, from leather finishes to wood grain. The process creates detailed textures by photographically applying an acid-resistant masking material to the mould surface and then etching the opened areas with acid.

You can adjust texture uniformity and gloss level to some extent through multiple etching steps or by blasting the surface with glass beads.

Coating: Mould components are coated for various reasons. Multiple coatings are used for their unique benefit to the mould.

Flash chrome and thin deposits of electroless nickel less than 0.001-inch thick offer protection against rust and corrosion. Thicker deposits of hard chrome, usually more than 0.002 inches thick, prolong the life of moulds running glass-filled or mineral-filled resins. Hard chrome and electroless nickel plating can also build thickness to correct dimensional problems or refurbish worn areas. Mould release coatings such as PTFE modified hard chrome, or electroless nickel has performed well in moulds with ejection problems such as medical parts with a preliminary draft.


What are the advantages of auto lamp mould manufacturing?

Although the mould design and manufacturing process is critical and complex (an inadequately designed mould can result in defects), it has some notable advantages too.

Here are a few points why manufacturing is beneficial for automotive lamps.


In the automotive business, repeatability (the ability to consistently produce identical parts) is crucial because automotive plastic injection moulding typically relies on robust metal moulds.

Computation and evaluation

The auto lamp mould-making process is an expensive process due to the cost of the mould. However, mass production of the moulds is beneficial to the manufacturer.

Moulding costs may increase if mould production falls below mass production.

Material availability

A vital benefit of making a mould with go4mould is that we have all the materials at hand. Manufacturers use a wide range of steel and aluminum.

Accuracy and surface finish

Mould manufacturing and using it is ideal for producing plastic parts with comparatively simple geometries, resulting in a high surface finish. Mould makers have many finish options when producing parts, including various surface textures—glossy, rough, or matte—applied directly to the mould.

Quick prototypes with rapid-tooling

Automotive mould manufacturers can turn around short runs of prototype moulded car components much faster than traditional (steel) tooling by making quick, low-cost aluminum moulds with rapid tooling or CNC machining.


What are the applications of auto lamp mould?

Figure 5: Applications of Auto Lamp Mold

Figure 5: Applications of Auto Lamp Mold

In the automotive industry, injection moulding is one of the efficient and predominant methods manufacturers apply to mould plastic. Go4mould produces many plastic components for a car; one of them is an auto lamp.

  • Exterior Lamps\Lights
  • Interior Lamps\Lights

Exterior Lamp\Lights: Moulding is a valuable process for many exterior automotive components, including auto lamps. Fine examples of it are headlights, indicating lamps, tail lights, header, and nose panels.

Interior Lamp\Lights: Go4mould also makes many automotive interior parts using the automotive plastic injection moulding process. Auto lamps are also a part of it. The door-light or dashboard lamp is moulded among dashboard faceplates, door handles, glove compartments, air vents, and more.


How many types of auto lamp mould are developed by go4mould?

Types of moulds

One of the most common mould types developed by go4mould, the two-plate Mould, consists of two mould halves, over each other, that open along one parting line. In this type, material enters the mould cavity directly via a sprue gate or indirectly through a runner system which delivers the material to the desired location along the parting line.

Another type of mould made by go4mould is a three-plate mould. It opens at two significant locations instead of one. Typically, a linkage system between the three mould plates controls the mould opening sequence.

Another configuration, the stack mould, lessens the clamping force required by multi-cavity moulds. In this type, multiple cavities are located on a singular parting line, and the required clamp force is the sum of the clamps needed by each cavity plus the runner system.


Does go4mould manufacture moulds in large quantities?
