Haixiong Plastic Machine | Advantages of Injection Molding for SP Series and All Electric Series Car Lights

Headline lenses, light guides, and daytime running lights - these components that directly determine the lighting effect and overall vehicle texture - are on the carThe most difficult "optical component" to injectHaixiong Plastic Machinery adopts a dual line layout of SP precision servo series and fully electric (fully electric) series, respectivelyHigh precision closed-loop controlandFully electric clean driveTwo dimensions provide a professional level solution for the molding of optical components for car lights.

　Focus on Models: SP Series · All Electric Series

The lenses, light guides, and daytime running light components in car lights are fundamentally different from ordinary structural components - they need to be both "visible" and "accurately made".Three core demandsDirectly determines equipment selection:

Optical grade quality

The lens and light guide strip require high light transmittance and low haze. Bubbles, flow marks, silver lines, and shrinkage marks will all be magnified on the light path. Injection must be smooth, uniform, and without fluctuations.

High repeatability accuracy

The optical surface shape and light distribution accuracy depend on the absolute consistency of injection volume, holding pressure, and position between each mold, and weight and position repeatability accuracy are the lifelines of yield.

Cleanliness and stability

Optical components are extremely sensitive to pollution, and defects may be caused by hydraulic oil mist, oil temperature drift, and vibration; Cleanroom and constant temperature process require equipment to be "clean and stable".

02. SP series: Precision molding platform for optical components of car lights

Born for "high-precision injection, short cycle, high response"

The official website of Haixiong positions the SP series in scenarios that require high-precision injection, short cycles, high response, and higher requirements for safety protection - the primary target scenario isOpticsNext, it covers 3C, thin-walled packaging, and precision gears.

The core advantages of the SP series for optical components such as headlight lenses and light guides are reflected in four dimensions:

　　Precision structure:The screw adopts spline connection, with uniform force distribution and stable plasticization; Shooting transferlinear guideLow friction and high guiding accuracy;Five point internal rolling locking mechanismThe template has good rigidity, small deformation, and stable accuracy under eccentric load - providing reliable support for asymmetric cavities such as thin-walled light guide strips

　　Accurate control:Dual closed-loop control of pressure and flow,Repetitive accuracy error<1%Strong anti-interference ability, ensuring consistency of batch products - this is the key to stable light distribution performance and avoiding "inconsistent brightness of the same batch of lights"

　　Quick response:High torque, low inertiaservo motorMatching improvementscrew pumpFast action response and short dry cycle, while ensuring the quality of optical componentsShorten the molding cycle

　Safety and energy conservation:Equipped with side mounted mechanical safety and inclined wedge type sliding feet for safe and reliable operation; Servo on-demand power supply, compared to traditional modelsEnergy saving of approximately 25% -60%And reduce the consumption of cooling water

　　Typical applications of car lights: precision parts with high precision and consistency requirements such as headlight lenses, light guide strips, daytime running light components, lampshade decorative frames, etc

Worth noting empirical evidence: In the customer feedback on car lights disclosed on Haixiong's official website, the production director of a car light company in Jiangsu stated that——The Haixiong high-end SP machine introduced last year helped us increase the yield of car lamp injection molding by 3 percentage pointsThe direct source of yield improvement is the decrease in product consistency and defect rate brought about by the SP series closed-loop control.

03. All electric series: the ultimate choice for "clean+high-precision" optical components

Fully servo driven, please take the hydraulic system out of the workshop

Small all electric "is one of the three official characteristic series of Haixiong, which together with medium-sized connecting rod machines and large two plate machines form Haixiong's product matrix. The fully electric series of locking, injection, ejection, and adjustment actions are all directly driven by servo motors, making it the forefront form of small precision optical component molding.

For the optical components of car lights, fully electric drive brings a challenge that hydraulic presses cannot simultaneously possessFour fold value：

Oil free and clean, guaranteed yield of optical components:The fully electric structure does not include a hydraulic system, which eliminates the contamination of optical surfaces by hydraulic oil mist and is naturally compatibleclean room——Components such as lenses and light guides that are extremely sensitive to cleanliness have better yield assurance

No oil temperature drift, more stable process:No hydraulic oil temperature fluctuations are transmitted to process parameters, injection speed and holding pressure remain stable throughout the entire process, and product weight and surface shape are consistentSuperior to hydraulic models

High precision and high repeatability:Servo motor direct drive, injection position accuracy and weight repeatability accuracy can reach higher levels, coupled with high response acceleration performance, suitable forMicrostructure light guide stripStable mass production of precision lenses

Energy saving and quiet, with lower operating costs:The motor provides energy on demand without continuous loss of hydraulic pump, and its energy consumption is significantly lower than that of traditional hydraulic presses; Low noise and low vibration, while improving the workshop environmentReduce vibration interference on precision molding

　　Typical applications of car lights: small lenses, light guide strips, ambient light optical components, microstructure optical components, and other precision components that require clean environments and high repeatability

04. Dual line collaboration: How to divide and combine SP and full power

SP and all electric are not a choice, but rather a production line for optical components of car lightsGold combination——Divide tasks according to component size and process requirements, and manage them uniformly within the same brand system:

　　*The SP series parameters are quoted from the product page of Haixiong's official website; The advantage of the all electric series lies in the universal characteristics of all electric injection molding technology in the field of precision optical components. Combined with the official positioning of Haixiong's "small all electric", the specific configuration is subject to the manufacturer's selection.

05. More than just a single machine: overall escort for the optical components production line of car lights

　　In mold monitoring equipment:Real time detection of the status of the ejector pin, slider, and insert during the mold closing stage; Identifying material shortages, flash edges, bubbles, color differences, and dimensional deviations during the molding stage, and supporting multi cavity inspection one by one - is the direct tool for "zero defect" management of automotive light optical components.

　Digital hot runner controller:Control accuracy ± 0.5 ℃, multi zone independent temperature control, providing a stable mold temperature environment for optical materials such as PC; A complete optical component forming solution is composed of ecological supporting equipment such as robotic arms, centralized feeding, and drying machines.

The essence of forming the optical components of car lights isPrecision, cleanliness, and stabilityThe unity of the three. The answer given by Haixiong Plastic Machinery is dual line parallel: the SP series maintains the accuracy and yield of medium and large precision parts with closed-loop control and high rigidity structure, while the all electric series achieves the ultimate cleanliness and high repeatability with full servo drive, and then completes the production line closed-loop with ecological matching such as in mold monitoring and hot runner control.

The improvement of yield rate based on customer empirical evidence of stacked car lightsOver 30 yearsWith the accumulation of servo technology, Haixiong Plastic Machinery provides a clear path for car lamp manufacturing enterprises from "single machine selection" to "optical component production line".
