The blow molding operation can achieve the purpose of high-temperature curing, namely, the powder coating on the surface of the workpiece is heated to a specified temperature and is kept for a corresponding time to be melted, leveled and cured, so that the workpiece surface effect required by people is obtained. Some blow molding operations have the following process steps: pushing the sprayed workpiece into a curing furnace, heating to a preset temperature (generally 180 ℃), and keeping the temperature for a corresponding time (15 minutes); opening the furnace, taking out and cooling to obtain a finished product. The needed relevant equipment is a curing oven, and the parameters needing to be automatically controlled comprise: the temperature and the heat preservation time can be controlled by adopting electric heating, fuel oil heating, gas heating, coal heating and other modes, and can be flexibly selected according to the energy conditions of the regions where people are located. The required related materials comprise a high-temperature curing oven (or oven) which can control the temperature and the holding time within a reasonable range.

wherein, in the field blow molding mechanism, the blow molding pump body is connected with the blow molding tap and used for providing blow molding power for the blow molding tap.

In addition, in the blow molding timing control system and method based on the transfer speed, the real-time processing equipment can be realized by adopting a GPU chip. The GPU is different from a DSP (Digital Signal Processing) architecture in several major aspects. All its calculations use floating point arithmetic and there is no bit or integer arithmetic instruction at this time. Furthermore, since the GPU is designed specifically for image processing, the storage system is actually a two-dimensional, segmented storage space, including a segment number (from which the image is read) and a two-dimensional address (X, Y coordinates in the image). Furthermore, there is no indirect write instruction. The output write address is determined by the raster processor and cannot be changed by the program. This is a significant challenge for algorithms that are naturally distributed among the memories. Finally, no communication is allowed between the processes of different shards. In effect, the fragment processor is a SIMD data parallel execution unit, executing code independently in all fragments. Despite the above constraints, the GPU can still efficiently perform a variety of operations, from linear algebraic sum signal processing to numerical simulation. While the concept is simple, new users are still confused when using GPU computations because the GPU requires proprietary graphics knowledge. In this case, some software tools may provide assistance. The two high-level shading languages CG and HLSL enable users to write C-like code and then compile it into a shard program assembly language. Brook is a high-level language designed specifically for GPU computing and does not require graphical knowledge. Therefore, it can be a good starting point for the worker who first uses the GPU for development. Brook is an extension of the C language, integrating a simple data-parallel programming construct that can be mapped directly to a GPU. Data stored and manipulated by the GPU is visually analogized to "streams" (streams), similar to the arrays in standard C. The Kernel is a function that operates on the stream. Calling a core function on a series of input streams means that an implicit loop is implemented on the stream elements, i.e. a core body is called for each stream element. Brook also provides reduction mechanisms, such as performing sum, maximum, or product calculations on all elements in a stream. Brook also completely hides all the details of the graphics API and virtualizes many user-unfamiliar parts of the GPU, like the two-dimensional memory system. Applications written in Brook include linear algebra subroutines, fast fourier transforms, ray tracing, and image processing. With the X800XT for ATI and the GeForce 6800Ultra type GPU for Nvidia, the speed of many such applications increased by as much as 7 times under the same cache, SSE assembly optimized Pentium 4 execution conditions.

Finally, it should be noted that each functional device in the embodiments of the present invention may be integrated into one processing device, or each device may exist alone physically, or two or more devices may be integrated into one device.

The functions, if implemented in the form of software-enabled devices and sold or used as a stand-alone product, may be stored in a computer-readable storage medium.
